What is the use of the <form> tag in HTML?

The

tag in HTML is specifically designed to collect user input. It functions as a container for various types of input elements, including text fields, checkboxes, radio buttons, submit buttons, and more. When a user fills out a form and submits it, the data captured can be sent to a server for processing, such as saving to a database or handling a user registration or login. This functionality makes form elements an essential part of web applications that require user interaction and data submission.

The other choices provided do not accurately describe the purpose of the tag. For example, while displaying images in a gallery might involve other HTML tags for structuring the content and applying styles, it is not related to the form functionality. Likewise, defining a navigation bar typically involves

elements or lists, and creating a responsive layout usually employs CSS for design flexibility rather than relying on the tag.
