Six people E, H, K, M, S and U are seated in a circle facing the centre. U and H are immediate neighbours of M. E is the only person sitting between K and S. H is to the immediate right of S. Who is to the immediate right of U?

The correct option is E.

Let us solve the seating arrangement step-by-step:

1. We have six people: E, H, K, M, S, and U sitting in a circle facing the centre. Facing the centre means that for any person, "left" is in the clockwise direction and "right" is in the counter-clockwise direction.

2. The problem states that H is to the immediate right of S. Let us place S at a position in the circle. Since H is to the immediate right of S, H will be placed next to S in the counter-clockwise direction:
Arrangement: (S, H)

3. Next, we are told that U and H are immediate neighbours of M. This means M is sitting directly between U and H. Since H is already placed, M must be on the other side of H. Thus, U must be on the other side of M:
Arrangement: (S, H, M, U)

4. We are also told that E is the only person sitting between K and S. Since we already have S placed, E must be next to S on the empty side, and K must be next to E:
Arrangement: (K, E, S, H, M, U)

5. Let us verify the circle of 6 seats:
- S is to the left of H (so H is to the immediate right of S).
- M is between H and U (so U and H are immediate neighbours of M).
- E is between K and S (so E is the only person between K and S).
- The circle is complete: U is next to K.

6. Now, we need to find who is to the immediate right of U.
Looking at the sequence (K, E, S, H, M, U) in clockwise order:
Going counter-clockwise (to the right) from U, the next person is K's neighbor, which is E.
Therefore, E is to the immediate right of U.
