Solution

The correct option is A Covalent way
Nitrogen atom has $7$ electrons in it, which can be written as $2, 5$ . Thus we see that Nitrogen atom has $5$ electrons in its outermost orbit. In a Nitrogen molecule, two Nitrogen atoms are present. Both the Nitrogen atoms have $5$ electrons in their outermost orbit. So, both the Nitrogen atoms need $3$ electrons more each to complete their octet so that they can have $8$ electrons in their outermost orbit.
So, the two Nitrogen atoms mutually share three valence pair of electrons between them, so that now both the atoms have $8$ electrons each in their outermost orbit and complete their octet. When two atoms mutually share their pair of electrons between them, a covalent bond is formed between the atoms.
Thus Nitrogen molecule is formed from Nitrogen atoms in a covalent way.
