Correct Option: B

Arya Samaj unequivocally condemned practices such as polytheism, iconolatry, animal sacrifice, ancestor worship, pilgrimage, priestcraft, the belief in Avatars or incarnations of God, the hereditary caste system, untouchability and child marriage on the grounds that all these lack Vedic sanction. It believed in the infallible authority of the Vedas, but outrightly rejected rituals, idol worship and all the pretensions in the name of religion.
