Which statement about labeling form controls is accurate?

• A. Always rely on the screen reader to read labels automatically.
• B. Use an aria-label on the input and skip label elements.
• C. Link labels to inputs with data attributes.
• D. Use an id on the control and set the label's htmlFor attribute to that id.

Answer: (D)

Connecting a label to its input by giving the input an id and using that id in the label’s htmlFor attribute is the reliable, accessible pattern. This creates a clear, explicit relationship so screen readers announce the label when the control is focused, and clicking the label will focus or activate the input. It also keeps a visible label for sighted users, which is maintained in a single, standard way across all form controls. Other approaches fall short because they don’t establish that robust, programmatic link. Relying on a screen reader to read labels automatically isn’t dependable, and using aria-label while skipping a visible label reduces clarity for sighted users. Using data attributes to “link” labels doesn’t create a real accessibility relationship, so assistive technologies won’t reliably associate the label with the control.
