To determine the correct answer, let's analyze the given options.

A. Equal amplitudes: Two opposite pulses can have different amplitudes and still exhibit incomplete cancellation. So, option A is not the correct answer.

B. Different energies: Since energy is related to both amplitude and frequency, two opposite pulses with different energies will not result in incomplete cancellation. So, option B is not the correct answer.

C. Equal pulses: This option suggests that opposite pulses are identical in shape and magnitude. Two opposite pulses with equal amplitudes and opposite signs will lead to complete cancellation. So, option C is not the correct answer.

D. Equal displacements: When two opposite pulses have equal displacements, they cancel each other partially but not completely, resulting in incomplete cancellation. Therefore, option D is the correct answer.

So, the correct option is D.
