General Studies · Seating Arrangement

Six students Annie, Bristo, Chintu, Dani, Emily, and Freight are sitting in a row facing North (not necessarily in this order): i) Dani is sitting second to the right of Chintu, who is sitting at the fourth place from the left end. ii) Three people are sitting between Freight and Dani, and Emily is sitting to the left of Annie. iii) Bristo and Chintu are not immediate neighbors. If Bristo interchanges positions with Emily, and Annie interchanges positions with Freight, which of the following couples will be sitting at both ends of the line?
