D Correct answer
Explanation

Any two of the three statements are sufficient to determine Vinita's present age. Each pair provides two independent equations relating Vinita's age and her son's age. For example, using statements I and II: from the ratio (V:S = 11:6) and the past relationship (V-5 = 2(S-5)), we can solve for unique values.
