Checkbox are used to . . . . . . . .

The correct answer is: D. fill multiple information.

Checkboxes are used to allow users to select multiple options from a list. This is in contrast to radio buttons, which only allow users to select one option from a list. Checkbox are often used in forms to allow users to specify their preferences or to indicate that they have read and agree to a set of terms and conditions.

Here are some examples of how checkboxes are used:

• In a contact form, you might use checkboxes to allow users to select their preferred method of contact (email, phone, or snail mail).
• On a product page, you might use checkboxes to allow users to select the features they want in a product (color, size, etc.).
• On a website’s privacy policy page, you might use checkboxes to allow users to indicate whether they agree to the website’s use of cookies.

Checkboxes are a simple but effective way to allow users to provide multiple pieces of information. They are easy to use and understand, and they can be used in a variety of contexts.
