Since E is between A and C, and A faces B while C faces D, it follows that D is opposite E.

The arrangement is A-B-C. Therefore, E is sitting next to D.

A is sitting to the immediate left of B, which means B is to the immediate right of A. Since C is to the immediate right of A, the arrangement is A-B-C. Therefore, A is sitting between B and C.

Since A is to the left of B, B is to the right of A. C is opposite A, so the arrangement is A-B-D-C-E-F. Therefore, D is to the right of B.

Since A is to the right of B, B is to the left of A. C is opposite A, so C is not next to B. Therefore, D must be to the left of B.

If E is to the left of F and G is to the right of F, then H must be opposite E.

If F is to the right of G, then H is to the left of F, making I opposite G.

Since I is opposite G, and G is next to H, the only person who can be next to I is J.

Since G is to the right of H, H must be to the left of G. Therefore, G is also the one sitting to the left of H.

Since J is next to K and L is opposite J, P must be next to L in the arrangement.

With L between M and N, and O opposite L, R must be sitting next to O.

Since L is to the right of K and M is to the left of K, N must be sitting opposite L.

Since M is opposite N and O is to the right of M, O will be to the left of N.

Since Q is opposite O, the only person who can be next to Q is R.

With O next to P and Q opposite P, S must be next to O.

With R to the right of S and T opposite R, we can determine that V is to the left of S.

Since T is between U and V, and W is opposite U, Z must be next to W in the circular arrangement.

The arrangement can be visualized as U-T-V-W-X-Y-Z. Therefore, V is sitting to the left of U.

Since T is next to U and V is opposite T, the only person who can sit next to V is Y.

With T to the left of U, it follows that U's right must be occupied by T, as V is opposite T.

Since U is between V and W, W is sitting next to V.

Since Z is next to A and B is opposite Z, A is sitting next to B.

If A is facing B, then the arrangement is such that D is to the right of B, as C is already established to the left of A.

With F to the right of G and H to the left of F, I must be opposite G in the arrangement.

Since O is opposite M, and M is next to N, P must be next to O.

The arrangement is M-N-O. If we assume a circular arrangement, the person directly opposite N would be S.

Since X is between Y and Z, and W is to the left of Y, it follows that Z is to the right of X, making X the answer.

Since X is between Y and Z, and W is opposite Y, the only person who can sit next to W is X.

Given that X is to the left of Y and Z is to the right of Y, the only person who can be directly opposite X is A.

If R is to the right of P, then S must be to the left of Q, as they are opposite each other.
