Destructive interference occurs when a crest of one wave overlaps with a trough of another wave, resulting in a reduction or cancellation of the amplitude of the resultant wave. Therefore, the correct choice that describes an instance of destructive interference is:
**when a crest and a trough overlap.**
**when a crest and a trough overlap.**
