C Correct answer
Explanation

Let n articles sold. Profit per article = SP - CP = 754 - 648 = 106. Total profit = 1696, so n = 1696 ÷ 106 = 16. This requires all three statements: I gives total profit, II gives CP, III gives SP. Any two statements are insufficient since profit alone doesn't give quantity, or CP/SP alone don't give profit.
