Correct Answer is C

Explanation

Choice A rationale: Leaning the client toward the wall may not provide sufficient support and could lead to a fall.
Choice B rationale: Assuming a narrow base of support does not provide adequate stability when a client is falling.
Choice C rationale: Lowering the client to the floor is a safety measure to prevent injury during a fall. It reduces the distance of the fall and minimizes the risk of injury.
