Arab traders first brought Islam to India.
Answer: Option D
Explanation:
From the point of view of the early Arab traders, India was the land that lied to the east of the Indus river. The Arab traders that crossed this river in order to do trade in India were amongst the first people who brought Islam to India.
The Arabs that came to India for trade were mesmerised by the wealth and prosperity of the Indian kingdoms. The same Arabs later invaded India with the intention of looting the kingdoms.
During their invasions, they also carried out forceful conversions of the residents to Islam. This is how Islam came to India.
