The correct answer is B. If the United States was to be partitioned in the same way India was, the partition would be based on religious groupings.
In 1947, India was divided into two countries, as a result of the uncontrollable religious tensions in its society: on the one hand, the Republic of India, made up of inhabitants of Hindu religion; and on the other, Pakistan, whose citizens professed the Islamic faith. In turn, later Pakistan was divided in two: Pakistan itself, and Bangladesh, although this division did not respond to religious reasons but ethnic tensions.
