question mark

A string of negligible thickness is wrapped several times around a solid cylinder, which is kept on a rough inclined plane. A man exerts a force F through the string as shown in figure and slowly rolls the cylinder up through a vertical height `h`. The work done by the man is? (angle of inclination is 30 degree.) A) F.h/2 B) F.h C) F.2h D) F.4h
