Solution

The correct option is B $2$
No. of electrons in the outermost shell of element $X = 6$
$∴$ In a covalent bond, we share one/more electron pairs. So, to form a covalent bond it needs one pair of electrons to complete its octet.
Hence, option B is correct.

Whenever a non-metallic combines with another non metal, sharing of electron takes place between their atoms and a covalent bond is formed. A covalent bond can also be formed between two atoms of the same non-metal. The shared electrons are counted with both the atoms due to which each atom in the resulting molecule gets an inert gas electron arrangement of 8 electrons (or 2-electrons) in the outermost shell eg : $H_{2}$ molecule.
