The Tripitaka, also known as the Pali Canon, is indeed one of the most important collections of Buddhist scriptures, written in Pali. It contains teachings attributed to the Buddha, forming the foundation of Theravada Buddhism.
1. Tripitaka as Primary Collection:
Assertion (A) is true as the Tripitaka is one of the primary collections of scriptures for Buddhists, and it forms the doctrinal core of Theravada Buddhism.
2. Tripitaka's Three Pitakas:
Reason (R) is also true because the Tripitaka is divided into three collections: the Vinaya Pitaka (rules for monastic discipline), the Sutta Pitaka (discourses of the Buddha), and the Abhidhamma Pitaka (philosophical and doctrinal analysis).
3. Conclusion:
Since both Assertion (A) and Reason (R) are correct, and Reason (R) correctly explains the assertion, the correct option is (A).
