What does autofocus do when applied to a select element on page load?

• A. Automatically selects the first option
• B. Activates the drop-down selection list for input when the page loads
• C. Highlights the control but does not open it
• D. Prevents focus until user interacts

Answer: (B)

Autofocus makes the element receive keyboard focus as soon as the page loads. For a select control, that focus typically brings up the options list so the user can start choosing immediately, effectively opening the drop-down when the page loads. This is why opening the list on load is the best description of what autofocus does for a select. It doesn’t automatically pick the first option, and while focusing a select often reveals the drop-down, the exact behavior can vary by browser. It simply ensures the control is ready for interaction as soon as the page loads.
