Solution

The correct option is D Statement 1 is not correct, but Statement 2 is correct.
Exothermic reactions give away heat. They have Negative change in enthalpy; whereas endothermic reactions absorb heat.
Breaking of covalent bonds require energy. This is because while making the bond, energy is added that holds the atoms together in molecules. So, when we break bond, this energy is released. When released, this energy is free to do other work. This energy is usually measured as heat.
