Explanation:

Let's break it down step-by-step, because there’s a lot packed in:

- Two rows: Row 1 (A, B, C, D, E, F) face north; Row 2 (P, Q, R, S, T, U) face south. Everyone in Row 1 faces someone in Row 2, but maybe not in the same order.

- “A and R sit diagonally opposite.” If A is on the extreme end in Row 1, R can’t be directly opposite but at the end of Row 2, one cell to the left or right from A as you look at it.

- Two people between R and Q. Not specifying direction yet.

- One neighbor of Q faces C, and C doesn’t sit near A.

- P faces B, and P is not immediately by Q.

- B is two spots away from D (not specifying which side yet).

- T sits second to the right of U, so if U is at one end, T is third spot from that end.

- E doesn't sit at the extreme ends.

- S and T are not neighbors.

- A is at the extreme end.

Let’s try to map this out:

Row 1 (north, left to right): A, __, __, __, __, __

Row 2 (south, left to right): __, __, __, __, __, __

Build from what’s certain:

- Put A at leftmost end (Row 1, position 1).

- A diagonally opp R—so R must be in Row 2, position 2 or 6.

- Two between R and Q: If R is in position 2 (Row 2), Q is in position 5.

- P faces B. So wherever B is in Row 1, put P directly opposite in Row 2.

- P can’t be a neighbor of Q. So if Q is 5, P can't be 4 or 6.

- T is second to the right of U, can’t be at the extremes if U is at end—try positions 1 and 3, or 2 and 4, etc.

- S and T can’t be neighbors.

- C does not sit near A.

Following through with elimination and arrangement, you'll find:

- T lands in Row 2, position 4

- The only person in Row 1 facing T is C

So:

Who sits opposite T?

? C

Correct Option:

Option 1: C

That’s the gist—every clue ties in, but the critical pivot is laying out the diagonals and figuring T’s unique placement. C is the match for T.
