The correct answer is E. Both are mechanical waves
As we know that sounds waves are longitudinal waves in which medium particles will oscillates parallel to the wave propagation.
While in ocean the waves are of both nature i.e. transverse and longitudinal both. Here the energy is transferred to all molecules inside the water by transverse nature of wave while in the case of surface the energy is transferred by longitudinal waves.
So here we can say that common thing between them is that both type of waves required medium particles to propagate energy through the medium.So all those waves which required medium particles to propagate energy then it is known as mechanical waves
For this problem, we can use Boyle's law, which states that for a gas at constant temperature, the product between pressure and volume remains constant:
