What HTML element is used to group related elements within a form?

The correct answer is the Fieldset Tag because it is specifically designed for grouping related elements within a form. Using the Fieldset Tag helps to logically organize the elements, such as input fields and labels, which improves both the visual layout and accessibility of the form.

When a Fieldset Tag is utilized, it typically comes with a legend that can provide a descriptive heading for the grouped elements, further clarifying the purpose of that section of the form for users. This semantic structure not only aids in organizing content but also helps screen readers to convey the information to users with visual impairments.

While the Div Tag can also group elements, it lacks the semantic meaning associated with forms, making it less appropriate for grouping form elements specifically. The Section Tag, although useful for grouping content in general HTML documents, is also not tailored for form elements and does not convey any specialized meaning related to forms. The Group Tag is not a standard HTML tag, and thus it would not be applicable in this context.
