Solution

The correct option is A Statement 1 and Statement 2 are correct and Statement 2 is the correct explanation of Statement 1
Energy can neither be created nor be destroyed. It is only converted in one form or the other. Addition of heat energy increases the kinetic energy which is dependent on absolute temperature.
$∴$ Temperature also increases when heat energy is added.
Hence, Statement 1 and statement 2 are correct and statement 2 is the correct explanation of statement 1.
