The IUPAC name of the structure is:

(A) 3-amino-2-formyl butane-1, 4-dioic. Acid
(B) 3-amino-2, 3-dicarboxy propanal
(C) 2-amino-3-formyl butane-1, 4-dioic acid.
(D) 1-amino-2-formyl succinic acid

Why is the correct answer option C and not option A? Can't we also name this compound by IUPAC nomenclature as 2-formyl-3-amino butane-1, 4 dioic acid? If we take the right carboxylic acid functional group COOH as 1, then number the Carbon atoms, then CHO takes 2, so formyl is 2, right? Also, doesn't formyl have greater seniority over amino?
