Answer is A as "A heat pump is a machine or device that moves heat from one location (the 'source') at a lower temperature to another location (the 'sink' or 'heat sink') at a higher temperature using mechanical work".
What Anand has said is not right no heat is converted to mechanical work, mechanical work is done to remove heat from lower temperature area and transfer it to higher temperature area.
Heat pump acts like removing heat from earth and delivering that heat to the sun by using mechanical work.
