Solution

The correct option is A
Water

Water has the ability to hold more heat as compared to other substances i.e for the same amount of heat supplied the rise in temperature for water is the least.

Also, water is not volatile while petrol and diesel are. Hence, water is used as a coolant in nuclear power plants.
