Step-by-step explanation:
The Indo-Aryans passed down their religious beliefs primarily through oral transmission by religious leaders. Initially illiterate, they utilized oral storytelling to convey the sacred hymns, rituals and rules of their Vedic religion. These hymns, called the Vedas, were not just religious chants but also encapsulated social laws and hierarchies.
Over time, as they settled into the Indian subcontinent, the Aryans created a complex society that revolved around these religious principles. The Vedas, which contained information on various deities like Varuna and Indra, were extremely significant in maintaining societal structure and religious observance. It was only later that these teachings were written down in the Sanskrit language as the people of the region became literate.
Rituals and sacrifices played a crucial role in Aryan society. The Vedic traditions emphasized the hierarchy of society with the Brahmans, who were knowledgeable about the rituals, occupying the highest level. These practices were integral to the preservation and transmission of their belief system from one generation to the next. The correct option is:B. Orally through religious leaders
