D. The amount of heat required to increase the temperature of 1 g of a substance by 1 °C.

Explanation:

Specific heat is defined as the amount of heat needed to raise a unit of mass of a compound by one degree on the temperature scale.

The gram is constituted as a unit of mass, and the degree Celsius as a unit of temperature, therefore, the specific heat can be defined as the amount of heat required to increase the temperature of 1 g of a substance by 1 °C.
