Answer:

B. Amplitude is the height of a wave.

Explanation:

Amplitude may have differing (and sometimes tricky) definitions. The most frequent, for symmetric waves) is one that declares an amplitude the change of a signal/wave-height from the zero-intercept/equilibrium point, or, similarly, half the difference between the maximum and the minimum peak within one period.


by definition, ans is B. Amplitude is the height of a wave.
