A Correct answer
Explanation

In DOM event handling, onKeyDown returning false prevents the key-press event from firing. The event sequence is keydown → keypress → keyup, and canceling keydown stops the chain. Options C and D are wrong because onKeyDown doesn't affect key-up, which always fires when the key is released.
