The correct answer is C. Islam. Soldiers brought Islam to South Asia in the early 700s. Muslim armies led by the Arab general Muhammad bin Qasim invaded the region and established the Umayyad Caliphate in Sindh, which is present-day Pakistan. Islam gradually spread in South Asia through various means, including trade, Sufi missionaries, and the establishment of Muslim dynasties such as the Delhi Sultanate and the Mughal Empire. To find the answer to this question, one can use historical sources or refer to textbooks and online resources that cover the history of South Asia and the spread of Islam in the region during that period.
