The correct answer is option 4: Buddhists. The Tripitakas, also known as the "Three Baskets," are the sacred scriptures of Buddhism. They are considered to be the most important and authoritative texts in the Buddhist tradition. The Tripitakas are written in the ancient Indian language of Pali and are divided into three sections: the Vinaya Pitaka (rules for monastic discipline), the Sutta Pitaka (discourses of the Buddha), and the Abhidhamma Pitaka (philosophical analysis and interpretation). These texts contain the teachings of the Buddha, including his doctrines on ethics, meditation, and the nature of existence. They serve as a guide for Buddhist monks and nuns, as well as for lay practitioners seeking to understand and practice Buddhism.
