Step-by-step solution

Structure A shows a benzene ring substituted at the 4-position with an isobutyl group and at the 1-position with a propanoic acid group. The IUPAC name is 2-(4-isobutylphenyl)propanoic acid, which matches R. Structure B shows a propane chain with three carboxylic acid groups at positions 1, 2, and 3, and a hydroxyl group at position 2. The IUPAC name is 2-hydroxypropane-1,2,3-tricarboxylic acid, which matches S. Structure C shows a hexanedial chain with bromine atoms at positions 2 and 3. The IUPAC name is 2,3-dibr
