Click for Explanation
B is correct. GABA has a four-carbon carboxylic acid backbone with an amino group at the fourth position (C-1 is the carboxyl carbon), making it 4-aminobutanoic acid.
The carboxy- prefix is only used when a compound contains more than one carboxylic acid group (Choice A). The carbon chain contains 4 carbons (butan-), not 3 carbons (propan-), which is why Choice C is incorrect. IUPAC nomenclature does not use Greek letters (Choice D).
