Answer: A - Theravada is a branch of Buddhism, not a sacred text (Mahayana Buddhism and Tibetan Buddhism are the other branches). Buddhism does have meaningful texts, but it does not have a central sacred text in the way that Christianity has the Holy Bible and Islam has the Qur'an. The Qur'an is the fourth of four revealed books or scriptures that are integral to the Muslim faith. The Tanakh is often called the Hebrew Bible, and it is essentially what the Protestant Christian Old Testament is (though the two texts have different chapter divisions). "Tanakh" is an acronym for the three components of the text: the Torah, the Nevi'im, and the Ketuvim. The Catholic and Eastern Orthodox Old Testaments are also mostly the same as the Tanakh (with the same chapter divisions as the Protestant version), but the Catholics and Eastern Orthodox churches use expanded versions of the text. The Upanishads are part of the Vedas, the oldest and most fundamental sacred text in Hinduism. The Upanishads occur at the end of the Vedas and are considered the apotheosis of all Vedic knowledge.
