Explanation:

In the study of waves (a topic in Physics, a subfield of Natural Science), the top part of a wave is defined as the crest. A trough is the bottom, wavelength is the distance between two crests (or troughs), and wave height is the vertical distance between crest and trough. So the correct term for the top of a wave is crest, corresponding to option C.
