The correct option is A.
Step-by-step explanation:
The religion that remains a predominant home in India, according to the options provided, is C) Hinduism. India is often labeled a Hindu state, which is a reflection of the fact that around 80 percent of the population follows Hindu traditions. This makes Hinduism the most practiced religion in the country. Islam is the second-most popular religion, practiced by about 13 percent of the population. While the Delhi Sultanate rulers were Muslims, contemporary India is a secular state with a diverse religious landscape, and Hinduism is the main religious tradition in India.
The rulers of the Delhi Sultanate in India were followers of Islam, which is a significant religious tradition in India's history. Throughout history, the northern part of India became increasingly Muslim, especially after the conquest of the Delhi Sultanate, while the south retained primarily Hindu cultural beliefs. It is also important to note that Christianity, Buddhism, and other religions have their presence in India, contributing to its diverse religious fabric.
