A Correct answer
Explanation

Alcohol disrupts the cytoplasmic membrane integrity (2), iodine oxidizes sulfhydryl groups in enzymes (1), acridine dyes intercalate into nucleic acids (4), and quaternary ammonium compounds denature proteins (3). The matching A-3, B-1, C-4, D-2 correctly pairs each agent with its primary site of action.
