C Correct answer
Explanation

Let A's present age be x and uncle's age be x+30. Five years ago: A was x-5, uncle was x+25. Given that (x-5) = (x+25)/4, solving gives x=15 (A's age) and uncle's age = 45. After 5 years, uncle will be 50. The key is setting up the age difference equation correctly and remembering that the age difference remains constant over time.
