उत्तर
If Assertion is INCORRECT but Reason is CORRECT.
Explanation:
The assertion is incorrect because the O-O bond length in ozone (127.8 pm) is not the same as in molecular oxygen (121 pm). However, the reason is correct; ozone is a resonance hybrid of two canonical structures, which explains why both O-O bonds in ozone are equal in length and intermediate between a single and double bond.
