Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Non-metallic atoms of the same element combine covalently.
The two atoms have the same electronegativities.
Hence, Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
Note: When electronegativity difference is zero, covalent bond is formed.
