The correct answer is option 1, Tripitakas. The Tripitakas, also known as the Three Baskets, are the sacred texts of Buddhism. These texts are considered the most important and authoritative scriptures in Buddhism and are divided into three sections: the Vinaya Pitaka, Sutta Pitaka, and Abhidhamma Pitaka.

Option 2, Upanishads, is incorrect. Upanishads are sacred texts in Hinduism that explore philosophical concepts and spiritual teachings.

Option 3, Angas, is also incorrect. Angas are scriptures in Jainism that contain rules and guidelines for monks.

Option 4, Aranyakas, is also incorrect. Aranyakas are part of the Hindu Vedic literature and are associated with rituals and sacrifices performed in the forest.

It is important to note that while Buddhism and Hinduism share some historical and cultural connections, their sacred texts and teachings are distinct.
