In which situation would a video call be more useful than a phone call?

Answer and explanation

Correct answer: When facial expressions or a demonstration also need to be seen

The governing concept is choosing a communication medium according to the information required. A phone call mainly transmits sound, whereas a video call transmits sound and moving images. If facial expressions, gestures, or a demonstration must be observed, the visual channel adds essential information. Therefore option D is correct. A short spoken word needs only audio, no internet prevents a video call, and a written record requires text.
