B Correct answer
Explanation

2 years ago, average age of A and B was 26, so their combined age was 52. Currently: A + B = 52 + 4 = 56. A's age 5 years hence = 40, so A's current age = 35. Therefore B = 56 - 35 = 21. B is 5 years younger than C, so C = 21 + 5 = 26. Difference between A and C = 35 - 26 = 9.
