• B. S is father of P.
• C. P is daughter of Q.
• D. None of these

Answer 1

The Correct Option is B

To interpret the expression "P Q - S," we start by deciphering each symbol and the relationships they represent:

• "P Q" means "P is the son of Q."
• "Q - S" means "Q is the wife of S."

Now, let's analyze the relationships step-by-step:

• "P Q" translates to "P is the son of Q."
• "Q - S" translates to "Q is the wife of S." Therefore, S is the husband of Q.

By combining these relationships, we see that:

• Q being the wife of S makes S the father of Q's children.
• Since P is the son of Q, and Q is married to S, it follows that S is the father of P.

Thus, the correct interpretation of the expression "P Q - S" is that S is the father of P.
