Answer:

D)It is transferred by convection and radiation.

Explanation:

Convection can be regarded as a model of heat transfer involving the transfer of thermal energy via movement of a fluids such liquid or gas. It's a process whereby heat is transferred by movement of a heated fluid. Radiation can be regarded as a model of heat transfer involving the transfer of thermal energy via thermal emission.

Therefore, when someone holds a hand above a fire it heat transfer occur through radiation because it happens through emmision of the heat and also convection as gas.
