None of the above

Detailed explanation-1: -Newton’s third law of motion describes action and reaction forces. The law states that for every action force, there is an equal and opposite reaction force.
Detailed explanation-2: -It is all in Newton’s third law: as your legs propel your body towards the dock, they also apply to the boat an equal force in the opposite direction, which pushes it away from the dock.
Detailed explanation-3: -A woman on a boat tries to step off the boat on to a pier. For every action, there is an equal and opposite reaction. Pushing your body forward will have an equal reaction backwards on the boat. NOTE: Forces always come in pairs: that is why Newton’s third law is sometimes referred to as his law of pairs.
Detailed explanation-4: -The boat moves backward when the sailor jumps in the forward direction because of Newton’s third law of motion which states that for every action, there is an equal and opposite reaction. Thus, when the sailor jumps in the forward direction he is causing an action force due to which the boat moves backward.
