If a projector displays the computer screen but presentation audio is absent, which additional component should be checked?

Answer and explanation

Correct answer: Audio output and speaker connection

The governing concept is that visual and audio outputs can follow separate signal paths. A projector may successfully receive the video signal while the computer is muted, using the wrong audio output, or lacking a proper speaker connection. Therefore, option D is correct. A mouse pad, scanner lid, or pen-drive name has no direct role in carrying presentation sound to the audience.
