A Correct answer
Explanation

From I: Amount = 10000(1 + r/100)² = 11025, giving (1 + r/100)² = 1.1025, so 1 + r/100 = 1.05 or r = 5%. From II: Amount = 10000 + 10000×r×2/100 = 11000, giving 10000 + 200r = 11000 or r = 5%. From III: Principal = 10000. I alone gives rate (assuming standard principal). II alone gives rate (assuming standard principal). III alone is insufficient. With III, both I and II individually give the rate. Any two statements are sufficient - III with either I or II, or I and II together.
