Who wrote Vedanta-Parijatasourabha, a commentary on the Brahma Sutra, in simple language?

Answer: Option A

Nimbarka's commentary on the Brahma-Sutras known as the Vedanta-Parijata-Saurabha, and that of his immediate disciple Srinivasa styled the Vedanta-Kaustubha are the chief works of the school of philosophy associated with the name of Nimbarka. The latter is not, however, a mere commentary on the former, as is sometimes wrongly supposed, but a full exposition of the views expressed I the Vedanta-Parijata-Saurabha which is very terse and concise and is not always clear. Both the treatises are therefore essential for the proper understanding of the doctrine of Nimbarka.
