Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
According to Hund's rule electrons are distributed among the orbitals of subshell in such a way as to give a maximum number of unpaired electron with parallel spin, i.e. in a subshell pairing of an electron will not start until and unless all the orbitals of that subshell will get one electron each with the same spin.
So, $N$ follows such configuration.
