How is Power defined in this context?

Explanation:
Power is about how fast work is done during movement. Work is the product of force and distance, and power takes that work and divides it by time, so power = work/time = (force × distance)/time = force × velocity. In exercise science, “strength” is the force muscles can produce and “speed” is how fast the movement occurs. Multiplying those together gives the rate at which work is performed—power. So interpreting the option as strength (force) times speed (velocity) matches the definition of power. The other ideas don’t fit: mass divided by acceleration isn’t a standard measure of work rate; velocity times time gives distance; and force times distance is work, not power.
