one reason that buddhism religion did not grow in india was because

of the Emperor Aurangzeb's rejection of Akbar's tolerant policies

Indian people were predominantly Hindu believers

of the growing influence of Confucianism

of the Islamic conquest of Sri Lanka

The correct reason is "Indian people were predominantly Hindu believers".

Buddhism originated in India and initially spread throughout the Indian subcontinent. However, over time, it declined and eventually became marginalized in its country of origin. One of the main reasons for this decline was because the majority of the Indian population adhered to Hinduism, which was deeply ingrained in the social and cultural fabric of the society. The rise of Hinduism as the dominant religion made it difficult for Buddhism to compete, leading to its decline in India.
