Solution

The correct option is C Assertion is incorrect but Reason is correct
Exothermic reactions release energy/heat.
Endothermic reactions absorb heat.
So Assertion is incorrect.
Increase in the energy can lead to loss of bond strength and finally breaking of the bond, Hence Breaking covalent bond always requires energy.
