What is the purpose of using fieldset and legend with related form controls?

• A. They are decorative
• B. They are only used for visual spacing
• C. They group related options and provide a label for screen readers; improves accessibility
• D. They replace the need for individual labels

Answer: (C)

Grouping related form controls with a fieldset and labeling that group with a legend provides semantic structure for the form and helps accessibility. The legend acts as a caption for the set, so screen readers announce the group’s purpose before listing its options, making it clear to users what the related controls are about. This is especially important for options like related radios or checkboxes, where understanding the context at a glance matters for efficient navigation. Fieldsets and legends are not just decorative or for spacing, and they don’t replace individual control labels—the per-control labels remain essential, while the fieldset/legend enhance the overall grouping and context for assistive technologies.
