Answer:
It's B, because of process of elimination:
A: The rower would be applying force to the oar not the other way around. So that's immediately out.
C: If the force of the oar applies to the water, the force of the water cannot apply to the oar.
D: Same as why A is incorrect.
So B is the only one left.
The correct answer is B. “Every action has an equal or opposite reaction”.
