General Studies · Seating Arrangement

Direction: Study the following information carefully to answer the question. Seven persons - B, C, D, E, F, G, and H are sitting in a row facing north, not necessarily in the same order. G sits three places away from D. Only one person sits between B and G. B sits neither adjacent to D nor at either of the extreme ends. The number of persons to the left of H is the same as the number of persons to the right of C. C sits to the right of G and to the immediate left of E. Four of the following five pairs are alike in a certain way based on their seating positions and thus form a group. Which one does not belong to that group?
