Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion In ground state electronic configuration of nitrogen, electrons are filled in orbitals as per Aufbau principle, Hund's rule of maximum spin multiplicity and Pauli's principle. So, the first three unpaired electrons filled in three orbitals.
