Answer: A) Forced

Explanation:

Forced convection is the highest heat transfer coefficient as, one of the reason is that when the hot air surrounded by the hot body are immediately removed by the air flow. In forced convection, the fluid is forced to flow over a surface or in tube by the external factors like a pump or fan. Convection heat transfer involves with fluid motion as well as heat conduction. The highest the velocity the highest the rate of heat transfer.
