The correct answer is: Both A and R is true but R is not a correct explanation of A.
Nalanda was a Buddhist monastery in India that was one of the most important centers of learning in the world. It was founded in the 5th century CE and flourished until it was destroyed by the Muslim invaders in the 12th century CE. Nalanda was a center of Buddhist learning, but it also attracted students from all over the world to study a variety of subjects, including philosophy, medicine, and astronomy. The Pala rulers were a dynasty of Indian kings who ruled from the 8th to the 12th centuries CE. They were patrons of Nalanda and other Buddhist monasteries. However, the fact that the Pala rulers patronized Nalanda does not mean that Nalanda was only a center of Buddhist learning. Nalanda was a center of learning for all subjects, and it attracted students from all over the world.
