Show answer and explanation

Correct answer: (D) I–R, II–S, III–Q, IV–P

Explanation

Vitamin E is an antioxidant protecting susceptible oil constituents. Calcium strengthens pectin networks and firms fruit. Edible wax slows moisture loss and shrinkage. Methyl bromide is the fumigant in the historical source list. Thus **I–R, II–S, III–Q, IV–P, D**; this is a matching question, not a recommendation to use that fumigant.
