A rower in a boat pushes the water backward using an oar.

What direction will the rower and the boat move?

A) Backward, because objects interact by exerting forces on each other in the same direction.

B) It is impossible to say unless you know whether the rower is accelerating or not.

C) Forward, because action-reaction forces are directed in opposite directions.

D) The water does not exert any force on the rower or the boat because the rower is doing the pushing.
