B Correct answer
Explanation

Statement II directly gives the ratio A:B as 3:2 and B:C as 2:1, which means A:B:C = 3:2:1. This completely determines the ratio of investments for all three persons. Statement I only gives A's contribution and the total, which doesn't establish the ratio between B and C. Therefore, statement II alone is sufficient while statement I is not.
