Explanation:

- First Law of Motion: An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force. The man must apply a force to change his state of rest.

- Second Law of Motion: Acceleration of an object depends on the net force acting upon it and the mass of the object. This explains how force causes motion but does not directly help the man move without an external force.

- Third Law of Motion: For every action, there is an equal and opposite reaction. The man can push against something to move toward the shore, illustrating this law.

- First, Second, and Third Laws of Motion: This option implies that all laws are needed, but primarily, he needs the third law.

Therefore, the correct answer is:

- Option 3: Third Law of Motion
