Explanation
Tablet is considered both a solid and a unit dosage form. A tablet is a solid dosage form because it is made by compressing or molding a powdered drug or combination of drugs. It is also a unit dosage form because it contains a specific amount of medication intended for a single administration. Therefore, the correct answer is "Both a and b."

Explanation
The statement given is false. Suspension is not a monophasic dosage form. A suspension is a two-phase system consisting of solid particles dispersed in a liquid medium. The solid particles do not completely dissolve in the liquid and tend to settle down over time, requiring shaking or stirring before use. Monophasic dosage forms, on the other hand, are single-phase systems where all the components are uniformly distributed throughout the dosage form. Examples of monophasic dosage forms include solutions and syrups.

Explanation
The correct answer is "All the above" because implants, films, and strips are all considered modern dosage forms. Implants are small devices that are surgically inserted into the body to release medication over a period of time. Films are thin sheets that dissolve in the mouth to deliver medication. Strips are also thin sheets that dissolve on the tongue or in the oral cavity for drug delivery. All of these dosage forms offer advantages such as convenience, ease of administration, and controlled release of medication.

Explanation
The correct answer is 200-500. This range indicates that the particle size of nanoparticles can vary between 200 to 500 nanometers. Nanoparticles are extremely small particles, typically smaller than 100 nanometers, and can have various applications in fields such as medicine, electronics, and materials science. The given answer suggests that the particle size range of nanoparticles can extend up to 500 nanometers, allowing for a wider range of potential applications and properties.

Explanation
In the second edition of the Indian Pharmacopoeia, the titles of the monographs were indeed changed from Latin to English. This change was made to make the information more accessible and understandable to a wider audience. By using English titles, it became easier for people who are not familiar with Latin to navigate and comprehend the content of the pharmacopoeia. This change aimed to improve the usability and effectiveness of the Indian Pharmacopoeia.

Explanation
Aerosol is a two-phase system because it consists of solid or liquid particles suspended in a gas. It can also be considered a three-phase system if we include the interface between the particles and the gas as a separate phase. Therefore, the correct answer is "Both a and b."

Explanation
The explanation for the given correct answer is that a hammer mill operates by using the force of impact to break down and pulverize materials. It consists of a rotating shaft with hammers attached to it, which strike and collide with the material being processed. This impact force causes the material to break into smaller pieces. Therefore, the statement "Hammer mill works on the principle of impact" is true.

Explanation
Neutral mixtures refer to mixtures that do not have any net charge or overall charge. Since neutral mixtures do not have any charge, they do not exhibit any electrical or chemical reactions. This lack of reactivity makes their behavior static, meaning that they do not change or show any dynamic properties. Therefore, the statement that neutral mixtures are static in their behavior is true.

Explanation
A membrane filter is designed to trap particles and microorganisms, including spores. The statement suggests that there are 400 to 500 million spores present on every square centimeter of the filter's surface. This indicates a high concentration of spores, highlighting the effectiveness of the filter in capturing and retaining these microscopic particles. Therefore, the statement is true.

Explanation
Special applications of Capsules include enteric coated capsules, sustained release capsules, and rectal capsules. Enteric coated capsules are designed to resist the acidic environment of the stomach and dissolve in the intestines, allowing for targeted drug delivery. Sustained release capsules release the medication slowly over an extended period of time, providing a prolonged therapeutic effect. Rectal capsules are designed to be inserted into the rectum for local or systemic drug absorption. Therefore, all the options mentioned above are correct as they represent different special applications of capsules.
