Five children are sitting in the row. S is sitting next to P but not T. K is…

To find the correct seating arrangement, we must systematically apply each constraint provided in the problem.

Step-by-Step Arrangement
Constraint 1: R is on the extreme left.

Arrangement: R, _, _, _, _

Constraint 2: K is sitting next to R.

Arrangement: R, K, _, _, _

Constraint 3: T is not sitting next to K.

Since K is at position 2, T cannot be at position 3. T must be at position 4 or 5.

Constraint 4: S is sitting next to P but not T.

We have positions 3, 4, and 5 remaining for S, P, and T.

If we place S, P, and T:

To ensure S is next to P and not T, let's try the sequence S-P-T.

Arrangement: R, K, S, P, T

Let's check the constraints:

R on the left? Yes.

K next to R? Yes.

T not next to K? Yes (T is at 5, K is at 2).

S next to P? Yes.

S not next to T? Yes (S is at 3, T is at 5).

Conclusion
In the arrangement R-K-S-P-T, S is sitting next to K and P.

Looking at the options:

Option A: P and T (Incorrect)

Option B: R and P (Incorrect)

Option C: Only K (Incorrect)

Option D: None of these (Correct, as the adjacent children are K and P)
