Explanation:

Let’s break this down:

- Saroja Vaidyanathan: She was a legendary Bharatanatyam dancer. The award’s name *Abhinandan Saroja* is similar to hers, but she’s not the recipient in 2021.

- Aparna Satheesan: She received the Abhinandan Saroja National Award in 2021 for her contributions to Bharatanatyam and Mohiniyattam. That’s the right answer.

- Mrinalini Sarabhai: Another giant in Indian classical dance, but she passed away in 2016, well before 2021, so it can’t be her.

- Alarmel Valli: An iconic dancer, but not the awardee for 2021.

So, yeah—option 2, Aparna Satheesan, is right.
