Answer:
e) Both are mechanical waves.
Step-by-step explanation:
As we know that mechanical waves are those type of waves which need medium to propagate from one point to other point
Here as we are comparing Sound waves and ocean waves then we can say that they both requires medium to travel from one end to other end.
So the common characteristic of the two waves is that they both requires medium to travel from one point to other point
So correct answer will be
e) Both are mechanical waves.
