Explanation:

- Narthaki Nataraj is a renowned Indian bharatanatyam dancer. She is the first transwoman to receive the Padma Shri Award for her contributions to Indian classical dance.

- Yamini Natrajan is not a widely recognized name in the context of this achievement. Perhaps a mix-up with another figure might have occurred here.

- Savitri Devi does not appear to be relevant to this specific context or recognition in Indian classical dance as a transwoman.

- Padma Valli isn’t known for this particular achievement either.
