On the basis of the information given in the questions, we find that C and D can take three positions as shown in the diagram following the restriction that C and D cannot be together  If P is true, then both Q and R have to be true. For S to be true, either Q or R must be false. Hence, if P is true, S cannot be true.

Direction: Answer the questions based on the following information.A, ...
Given Information:
- A, B, C, and D are to be seated in a row.
- C and D cannot be seated together.
- B cannot be seated at the third place.
- P, Q, R, and S are four statements.
- The relation between these statements is as follows:
- If P is true, then Q must be true.
- If Q is true, then R must be true.
- If S is true, then either Q is false or R is false.

To find:
Which of the following must be true?

Analysis:
We need to analyze the given statements and determine the possible outcomes based on the given conditions. Let's analyze each option:

a) If P is true, then S is false:
- This option does not provide any direct relation between P and S.
- It does not mention anything about Q or R.
- Therefore, we cannot determine the truth value of S based on the truth value of P alone.

b) If S is false, then Q must be true:
- This option provides a direct relation between S and Q.
- If S is false, then Q must be true according to the given statements.
- However, we cannot determine the truth value of P or R based on this option.

c) If Q is true, then P must be true:
- This option provides a direct relation between Q and P.
- If Q is true, then P must be true according to the given statements.
- However, we cannot determine the truth value of S or R based on this option.

d) If R is true, then Q must be true:
- This option provides a direct relation between R and Q.
- If R is true, then Q must be true according to the given statements.
- However, we cannot determine the truth value of P or S based on this option.

Conclusion:
Based on the given information and analysis of the options, the only statement that must be true is:
- If S is false, then Q must be true (Option b).
- Therefore, the correct answer is option 'A' - If S is false, then Q must be true.
