B Correct answer
Explanation

Let Shivani's current age be x and her mother's age be y. Five years ago: (y-5) = 3(x-5), meaning mother was 3 times as old as Shivani. After 5 years: (y+5) = 2(x+5), meaning mother will be twice as old. From second equation: y = 2x + 5. Substituting into first: 2x = 3x - 15, giving x = 15. Shivani is 15 years old today. Option B is correct.
