c. Hinduism.

Explanation:

Polytheism is a religious or philosophical conception based on the existence of various divine beings or gods. In most religions that accept polytheism, different gods and goddesses are representations of forces of nature or ancestral principles and can be seen as autonomous or as aspects or emanations of a creative deity or transcendental absolute principle (monistic theologies), that manifests itself immanently in nature. Polytheism is a type of theism. Within theism, contrasts with monotheism, the belief in a singular God, in most cases transcendent.

Hinduism is a polytheistic religion native to India that lacks a structured and homogeneous belief system but in which it is very important to follow the sacred texts, Vedas, and certain rules of conduct (respect the social caste system, follow a marriage ritual, etc). It is characterized by believing in reincarnation and the existence of a supreme being (Brahma) in which the soul of man aspires to be diluted when released from the body and manages to abandon its karma. However, Hindus believe in a great number of gods, some say this number goes up to 33 million gods.
