Quizplus · Accepted Answer

Resonance occurs when the frequency of the external sound wave matches the natural frequency of the tuning fork. In this case, the tuning fork has a frequency of 200 Hz, so it will resonate with a sound wave of the same frequency (option B). The other options are not matching the frequency of the tuning fork and therefore, won't cause resonance.
