After understanding the assertion and reason, choose the correct option.
Assertion : In the bonding molecular orbital $(MO)$ of $H_2,$ electron density is increased between the nuclei.
Reason : The bonding $MO$ is ${\psi _A}\, + \,\,{\psi _{B,}}$ which shows destructive interference of the combining electron waves.

Bond energies in $NO,\,N{O^ + }$ and $N{O^ – }$ are such as
