Concept:The area under a force-velocity graph is obtained by multiplying force and velocity, which gives power.Explanation:In a force-velocity graph, each small strip has area equal to $\text{force} \times \text{velocity}$.According to physics, $\text{Power} = \text{Force} \times \text{Velocity}$.Hence, the total area under the graph represents the total power.Energy, momentum, and pressure are not obtained from the product of force and velocity.Therefore, the correct choice is power.Answer:C. power
