Correct answer (B) 1 Solution We are given: 1. P looks at Q. 2. Q looks at R. 3. P is Married (M). 4. R is Unmarried (U). We do not know the status of Q. Let's consider the two possible cases for Q: Case 1: Q is Married (M). P(M) looks at Q(M): This is a (Married, Married) pair. Q(M) looks at R(U): This is a (Married, Unmarried) pair. Total such pairs = 1. Case 2: Q is Unmarried (U). P(M) looks at Q(U): This is a (Married, Unmarried) pair. Q(U) looks at R(U): This is an (Unmarried, Unmarried) pair. Total such pairs = 1. In both possible scenarios, there is exactly 1 pair where a married person is looking at an unmarried person. Turn this into a strength.
