C Correct answer
Explanation

Statement I gives quantity (20 sets) but not cost per set. Statement II gives selling price per set (Rs. 18000) but not quantity. Profit = 20% means profit amount = 0.2 × selling price. Total profit = profit per set × number of sets. Neither alone gives total profit: I lacks price, II lacks quantity. Together: profit per set = 0.2 × 18000 = Rs. 3600, total profit = 3600 × 20 = Rs. 72000. Both are needed, so C is correct.
