Carnot cycle represents process of an ideal heat engine which has maximum efficiency of conversion of heat energy into mechanical energy. So, A is right. The efficiency of a Carnot cycle depends only on the temperature of heat reservoirs is source and sink. So, reason is right and reason explains assertion.
