Solution

The correct option is C Assertion is correct but Reason is incorrect
Heat is carried away from a fire sideways mainly by radiation. Above the fire, heat is carried by both radiations and also by the convection of air. The latter process carries much more heat. So the assertion is correct but the reason is incorrect.
