Hint:

For arrangement problems, convert statements into direct order relations, then link them to form a full sequence.

Answer 1

The Correct Option is A

Step 1: Write down the conditions:
- P is to the right of Q. This means Q comes before P in the row.
- T is to the left of R and also to the right of P. So P comes before T, and T comes before R.
- Q is to the right of S, meaning S comes before Q.
Step 2: Arrange step-by-step:
From "S before Q" and "Q before P": S → Q → P.
From "P before T before R": P → T → R.
Step 3: Combine: S → Q → P → T → R.
Step 4: In this arrangement, the middle house (3rd position) is $\mathbfP$.
