Correct answer: D

Jyoti is 3 places to the right of Ananya, so from the left she is $8 + 3 = 11$ th.
Jyoti is 11th from the left and 15th from the right.
Total $= 11 + 15 - 1 = 25$ .

Worth noting

22 is $8 + 15 - 1$ , which treats Ananya's position as Jyoti's. '3rd to the right' means 3 places further, not 3 people in between.
