Answer:

option (c)

Step-by-step explanation:

Specific heat capacity of a substance is defined as the amount of heat required to raise the temperature of substance of mass 1 kg by 1°C.

Its SI unit is J/kg°C.

Heat capacity is defined as the amount of heat required to raise the temperature of substance by 1°C.

Its SI unit is J/°C

The relation between the specific heat capacity and the heat capacity is

specific heat capacity = heat capacity x mass

So, the specific heat of coffee mug = 240 x 0.25 = 60 J/kg°C

Thus, option (c) is correct.
