Difference b/w confirm and alert
- A.
  
  Both are same
- B.
  
  Confirm provides choice
- C.
  
  Alert provides choice
- D.
  
  None
Correct Answer
B. Confirm provides choice

Explanation
The given answer correctly states that the main difference between confirm and alert is that confirm provides a choice or option to the user, whereas alert does not. Confirm displays a pop-up box with a message and two buttons (usually "OK" and "Cancel") allowing the user to choose between different options. On the other hand, alert only displays a pop-up box with a message and an "OK" button, providing the user with no choice or options.

Is JavaScript case sensitive?
- A.
  
  Yes
- B.
  
  No
Correct Answer
A. Yes

Explanation
JavaScript is case sensitive, meaning that it distinguishes between uppercase and lowercase letters. This means that variables and function names must be written with the exact same casing each time they are used. For example, a variable named "myVariable" is not the same as "myvariable" or "MyVariable". Therefore, it is important to be consistent with casing when writing JavaScript code to avoid potential errors or bugs.

Correct Answer
A. An unvisited link is underlined and blue.

By default, an unvisited link is underlined and blue. This is a common convention in web design to indicate to users that the link has not been clicked on yet. When a user clicks on a link and visits the page, the link becomes a visited link and is typically underlined and red. An active link, on the other hand, is underlined and purple to indicate that the user is currently interacting with it. Therefore, the correct answer is that all of the given statements are true about links by default.

- D.
  
  All
Correct Answer
B. XML is used for exchanging data, HTML is not.

Explanation
XML (Extensible Markup Language) and HTML (Hypertext Markup Language) are both markup languages, but they serve different purposes. HTML is primarily used for creating web pages and displaying content on the internet. It focuses on how the content should be presented to the user, including text formatting, links, images, etc. On the other hand, XML is a flexible language that is used for storing and exchanging structured data. It allows users to define their own tags, making it highly customizable and adaptable to various data formats. Unlike HTML, XML is not concerned with presentation, but rather with the organization and structure of data. Therefore, the correct answer is that XML is used for exchanging data, while HTML is not.
