  1. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
  2. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
  3. Assertion is correct but Reason is incorrect
  4. Assertion is incorrect but Reason is correct

A
Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
B
Assertion is correct but Reason is incorrect
C
Assertion is incorrect but Reason is correct
D
Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Solution
Verified by Toppr


(I) is non-aromatic and (II) is antiaromatic.
Non-aromatic compounds are more stable than antiaromatic.
Hence, (I) is a stronger acid than (II).
Hence, it has lower pKa value.
Thus, Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
