Explanation: Condition: Jack sits next to Nick (J-N). Cond 2: J sits next to O or N, not both. So O is NOT next to J. Cond 3: K sits next to N (K-N-J or J-N-K). Cond 1: M is NOT next to J. The two people next to J are N and X. X is not M. X is not O. So X must be L or K. Case 1: X=K. The arrangement is J-K-N. The remaining people are L, M, O. The arrangement must be J-K-N-L-M-O (Cond 4 is not applicable). In a circular table of 6 people, the seating is J, K, N, L, M, O. Opposite pairs are (J, L), (K, M), (N, O). I. K sits next to L (FALSE). II. N sits directly opposite M (FALSE, N is opposite O). III. L sits next to J and O (TRUE). **I is False**.
