Which of the following Indian School of Philosophy rejects the Vedic Authority ?

Charvaka (Lokayata) Philosophy is a heterodox (Nastika) materialist school of Indian philosophy that completely rejects the epistemic authority of the Vedas, the existence of an immortal soul, and karma. By contrast, Samkhya, Nyaya, and Vaisheshika are orthodox (Astika) schools that accept Vedic authority.
