C Correct answer
Explanation

Let the person's age be x years. Then grandmother's age is x + 50 years. After 6 years: (x + 6) + (x + 50 + 6) = 152. Solving: 2x + 62 = 152, so 2x = 90 and x = 45. Present ages are 45 years and 95 years. Option D (25, 75) has the correct 50-year difference but wrong sum when checked.
