C Correct answer
Explanation

Starting from the end and working backwards: Rupak got 9 chocolates, so before the final division there were 36 (9 × 4). Before Saurabh took his share: 36 ÷ 3 × 4 = 48. Before Kavya took her share: 48 ÷ 3 × 4 = 64. Before Indu took 16: 64 + 16 = 80. The key insight is that after each person's division, 3/4 remain for the next step, so we multiply by 4/3 working backwards.
