General Studies · Seating Arrangement

Six students A, B, C, D, E, and F are sitting in a row facing North (not necessarily in this order). i) C is sitting immediately to the right of the person who is sitting second to the right of D. ii) There are three people between F and C, and A is sitting at the extreme right end of the line. iii) B and C are not immediate neighbors. If B interchanges its position with E, F with C, and A with D, then who will be sitting at the two extreme ends of the line?
