(a) Longitudinal wave: In a longitudinal wave, the particles of the medium oscillate parallel to the direction of wave propagation. Energy is transferred through compression and rarefaction of the particles. As the wave travels, the particles pass the energy to neighboring particles, resulting in a net transfer of energy.

(b) Progressive wave: A progressive wave refers to a wave that propagates through a medium, carrying energy from one point to another. It can be either a longitudinal or a transverse wave. In both cases, there is a net transfer of energy as the wave moves through the medium.

(c) Transverse wave: In a transverse wave, the particles of the medium oscillate perpendicular to the direction of wave propagation. Energy is transferred by the up-and-down motion of the particles. As the wave travels, the particles transmit the energy to neighboring particles, resulting in a net transfer of energy.

(d) Stationary wave: A stationary wave, also known as a standing wave, is formed by the superposition of two waves of the same frequency and amplitude traveling in opposite directions. In a stationary wave, the particles of the medium oscillate in fixed positions, resulting in regions of constructive and destructive interference. There is no net transfer of energy by the particles in a stationary wave.

Out of these options, the correct answer is (d) stationary wave. Unlike longitudinal, progressive, and transverse waves, a stationary wave does not involve a net transfer of energy by the particles of the medium.
