Solution

The correct option is C Both A and B
  • The skeleton of the fish is covered with strong muscles.
  • During swimming, muscles make the front part of the body curve to one side and the tail part swings towards the opposite side. The fish forms a curve.
  • Then, quickly, the body and tail curve to the other side.
  • This makes a jerk and pushes the body forward. A series of such jerks make the fish swim ahead. This is helped by the fins of the tail.
Hence the correct option is C.
