Given below are two statements, one labeled as Assertion (A) and the other labeled as Reason (R). **Assertion (A):** Although Nalanda became a great Buddhist university centuries later, it was already a significant stop during Gautama Buddha's frequent travels between Rajgir and Vaishali. **Reason (R):** The Mahaparinibbana Sutta records that Buddha delivered his famous discourse on the nature of virtue (the 'Sila' section of his teachings) at Pavarika's mango grove in Nalanda. In the context of the above statements, which of the following is correct?

Options:

• A: Both (A) and (R) are true but (R) is not the correct explanation of (A).
• B: Both (A) and (R) are true and (R) is the correct explanation of (A).
• C: (A) is true but (R) is false.
• D: (A) is false but (R) is true.
