Which of the following creates a table that is responsive to screens of different sizes?

The correct choice, which creates a table that is responsive to screens of different sizes, utilizes a <div> element with the class "table-responsive." This specific class typically comes from a CSS framework like Bootstrap, which is designed to make web components adapt dynamically to varying screen sizes.

When the "table-responsive" class is applied, it allows the table to scroll horizontally on smaller screens rather than having it overflow or appear squished. This enhances accessibility and usability for users on devices with different screen dimensions, ensuring that the content remains readable.

The other options do not provide the necessary responsive features. For instance, using just a div with the "table" class does not imply any responsive behavior, nor does having a container class. Similarly, a standalone table with just the "table" class lacks the wrapping structure needed for a responsive design. Hence, the selected option is the most effective in achieving a responsive layout for tables across different devices.
