JEE Advanced Chemistry question

Statement 1: The IUPAC name for the compound, NC-CH_2-CH_2-COOH is 3-cyano propanoic acid Statement 2: is considered as substituent group while is considered as the principal functional group

(A)Assertion is True, Reason is True; Reason is correct explanation for Assertion
(B)Assertion is True, Reason is True; Reason is not correct explanation for Assertion
