Therefore, the correct answer is "all of the above" as the internet is used for all these purposes.

Explanation
E-mail is a form of online communication that allows users to accept, forward, and store messages. It is a widely used method of sending and receiving messages electronically, allowing individuals to communicate with others across different platforms and locations. E-mail provides a convenient and efficient way to exchange information, documents, and media files, making it a popular choice for both personal and professional communication.

Explanation
Instant messaging is the correct answer because it refers to the communication method that involves instantly sent texts between two or more people. Unlike email, which may have a delay in delivery, instant messaging allows for real-time conversations and quick exchange of messages. Social networking, on the other hand, involves a broader concept of connecting and interacting with others through online platforms, which may include features like instant messaging but also encompass other forms of communication and content sharing.

Explanation
Social networking platforms allow individuals to create profiles and connect with their friends' profiles. These platforms provide a space for users to share personal information, photos, and updates with their network of friends. Users can also communicate with each other through messaging features, comment on each other's posts, and engage in various activities such as joining groups or events. Social networking facilitates social connections and allows people to stay connected and interact with their friends and acquaintances online.

Therefore, the statement that you should always end an email with thanks, sincerely, or thank you is true.
