General Studies · Linear Seating Arrangement

Ten people are sitting in two parallel rows, five in each row, in such a way that there is an equal distance between adjacent persons. Row I contains A, B, C, D, and E, all of whom are facing south. Row II contains P, Q, R, S, and T, all of whom are facing north. Thus, each person is sitting opposite a person from the other row. A is sitting at the right end of his row (from the perspective of a person facing south) and facing T. R is sitting in the middle of his row and facing C. E is sitting between C and D, and D is sitting at the right end of his row (from the perspective of a person facing south). Who is sitting exactly opposite B?
