When the particles of a medium move with simple harmonic motion, this means the wave is necessarily a

a. sinusoidal wave
b. transverse wave
c. harmonic wave
d. sound wave
e. longitudinal wave

a. sinusoidal wave

Explanation:

As we know that the medium particle will move in SHM when disturbance travel through the medium

Here the wave propagation through many ways are possible through the medium

When medium particles performs SHM then in that case the wave equation is given as

so we have above equation of wave must be sinusoidal equations

so correct answer will be

a. sinusoidal wave
