D Correct answer
Explanation

Let Tanya's current age be T. Priya is 2 years older than twice Tanya's age, so P = 2T + 2. After 2 years: P + 2 = 2(T + 2), which gives 2T + 4 = 2T + 4. This simplifies to 0 = 0, an identity that is always true. This means the second condition gives no additional constraint - it's satisfied for any value of T. Without knowing Tanya's actual current age, we cannot determine a specific age difference after 3 years.
