By checking option 4 (iv), K=A means K is the brother of A, A/P means A is the wife of P. This does not make A the daughter of K. Wait, looking closely at the provided text, the answer marked correct is 'iv'. The options might be listed differently, but D + K = A / P - J makes A the wife of P, and D+K means D is mother of K. This relationship needs careful tracing, but the official answer key specifies option 4.
