Which sense is useful for observing sound?

Answer and explanation

Correct answer: Hearing

The direct answer is C, hearing. Sound is a vibration that reaches the ear, and the sense of hearing allows the brain to recognise it. To observe sound in ordinary life, we listen and notice its loudness, pitch, or duration. Option A, sight, helps us observe light, shape, and colour; it cannot directly hear sound, although we may sometimes see an object vibrating. Option B, touch, can sometimes detect vibrations, but it is not the normal or primary sense for observing sound. Option C is correct because ears receive sound waves. Option D, taste, detects substances in food and does not detect sound. Exam cue: sound is heard, light is seen, and an odour is smelt.
