JEE Main Chemistry question

Statement 1: In sodium formate, both the C–O bonds have same value, 1.27 Å. Statement 2: Same bond length is due to the phenomenon of resonance.

(A)Assertion is True, Reason is True; Reason is correct explanation for AssertionCorrect
(B)Assertion is True, Reason is True; Reason is not correct explanation for Assertion
(C)Assertion is True, Reason is False
(D)Assertion is False, Reason is True

Answer: (A)
