Which of the following describes work? A. Energy acts on an object. B. Force acts on an object. C. Force acts on an object and causes a displacement of that object. D. Friction only acts on an object and causes a displacement of that object.

C. Force causes displacement

I believe the correct answer from the choices listed above is option C. Work is when force acts on an object and causes a displacement of that object. Work is calculated by multiplying force applied on an object and the distance it traveled. Hope this answers the question.
