Solution

The correct option is D Both Assertion and Reason are incorrect
For the bond between the atoms to be covalent, the difference between electronegativity should be less than $1.7$ . A covalent bond is formed by sharing of an electron pair between any $2$ atoms. Thus both assertion and reason are incorrect.
