A man uses oars to paddle a boat across a lake, as shown below. The subsequent motion of the boat is best explained by Newton's
law of action-reaction. Why? * A) As each oar pushes the water, the water pushes back, making the boat move forward.
B) The mass of the oars is more than the mass of the man, which makes the boat move forward.
C) The gravitational pull on the oars makes the boat move foward.
D) The water is in motion and will remain in motion until the oars make it stop, pushing the boat forward.
