Not by reheating.

Due to reheating heat supply more efficiency decrease but only work increase.

Steam turbine Reheat and regeneration increase efficiency.

Reheat may increase or decrease efficiency depending on mean temperature of heat addition. In this question it is asked "may" be improved. So reheat will also be the answer. Hence D is correct.
