The correct option is A U
Given, W sits directly opposite to T so, Z will be at head's table.
Again, Y and V always sit next to each other and V never sits next to Z
So, W and T are to the opposite side of the nearest corner of Z.
Again, U always sits in one of the two seats farthest from the head of the table. So, between U and T or W, X will sit.
Hence, U sits next to X.
