D Correct answer
Explanation

Let Rahul's age = 8x + 9, Suresh's age = 7x + 9 (9 years ago). After 6 + 9 = 15 years: (8x + 24)/(7x + 24) = 5/6. This gives 48x + 144 = 35x + 120, or 13x = -24, giving negative x. The system is inconsistent, making the data inadequate to determine Suresh's present age.
