B
The supply of energy is limited, so energy must be conserved
C
The total energy input to a system is equal to the useful energy output
D
The total energy in a closed system is constant
Correct option is C. The total energy in a closed system is constant
Principle of conservation of energyThe total energy in a closed system is constant.
The energy can not be created and destroyed only transfer from one form to another form.
Hence, C is correct option,
