    From I: If all of them face the centre, it means if A sits second to the left of B, then B should sit second to the right of A. But here Amit and Arun are different persons. Hence all of them do not face the centre
    From II: Again suppose of them face the centre like KEN. Ali sits third to the left of ken. Now, if Amit sits on the left of Ali obviously ken should be his neighbour. But the statement says otherwise. Hence our assumption is disproved. All of them do not face the centre.

    Correct Option: C
