We are given the following seating arrangement:
- Sruti and Manju are sitting in the centre.
- Anu and Priya are at the ends.
- Radha is sitting to the left of Anu.
Thus, the arrangement from left to right will be:
\[
\text{Anu} - \text{Radha} - \text{Sruti} - \text{Manju} - \text{Janaki} - \text{Priya}
\]
Now, the person to the right of Priya is Janaki. Therefore, the correct answer is (3) Janaki.
