Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Option (A) is correct.Explanation is correct reason for statement.
${N O}_{2}^{+}$ has no unshared electrons and it is linear. ${N O}_{2}$ has one unshared electron while ${N O}_{2}^{-}$ has one unshared electron pair.
