D Correct answer
Explanation

Statement I gives CP = 252 - 52 = 200. Statement II: Without discount, profit = 80, so MP = 200 + 80 = 280. Discount = 280 - 252 = 28. Discount% = 28/280 = 10%. Statement III: 40% profit means MP = 200 × 1.4 = 280, which is same as Statement II. So I and either II or III are sufficient. Statement II and III give the same information (either one works with I).
