D Correct answer
Explanation

Let Sunita's age be x. Father's age = 4x. After 8 years: 4x + 8 = 3(x + 8). 4x + 8 = 3x + 24. x = 16.

AI explanation

Let Sunita's present age be x, making her father's age 4x. After 8 years, their ages will be x + 8 and 4x + 8, and the father will be three times as old, so we can write the equation 4x + 8 = 3(x + 8). Expanding the right side gives 4x + 8 = 3x + 24, which simplifies to x = 16. Sunita is 16 years old today.
