Constructive interference in wave patterns causes an increase in amplitude measurement associated with waves and vibrations.
When two waves move in the same direction and are in phase with each other, their amplitudes are summed to produce the resultant wave.
The waves are considered to have suffered constructive interference in this case. Upward displacement occurs when waves experience constructive interference.
The medium's upward displacement is higher than the displacement of the two interfering pulses.
Hence option D is correct.
