B Correct answer
Explanation

Shilpa's age 3 years ago was x, so her current age is x+3. Arpita's age is thrice Shilpa's current age: 3(x+3) = 3x+9.

AI explanation

Let Shilpa's present age be S, making Arpita's present age 3S. Three years ago, Shilpa's age was S - 3, which is given as x. This means S = x + 3, and substituting this into Arpita's age gives Arpita's present age as 3(x + 3), which simplifies to 3x + 9.
