Correct answer is (c) 3

For explanation I would say: With five electrons in its outer most shell, it needs three more electrons to have a complete shell consisting of eight electrons which is the noble electronic configuration. The ion formed by the nitrogen atom is N^3-. It attains the electronic configuration on neon.
