Option a is the correct answer. The correct order of Vedic literature is as follows: The four Vedas or Vedic Samhitas i.e. the Rig, Sama, Yajur, and Atharva, and their Samhitas. The Brahmanas The Aranyakas The Upanishads Important Tips Brahmanas: The Brahmanas explain the hymns of the Vedas. They are written in prose and they elaborately describe the various sacrifices and rituals, along with their mystical meanings. Each Veda has several Brahmanas. Aranyaka: The Aranyakas are called forest books and they deal with mysticism, rites, rituals and sacrifices. They form the natural transition to the Upanishads. They offer the bridge between Karma marga (way of deeds) which was the sole concern of the Brahmanas and the Juana marga (way of knowledge) which the Upanishads advocated.
