Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
For diatomic molecules, the energy required to break the bond in one mole of a gaseous molecule is called bond dissociation energy or simple bond energy. For polyatomic molecules, average bond energy is taken as the dissociation bond energy.
If the bond energy is greater, then it is highly stable and do not react with other molecules, hence less reactive.
