          Answer & Explanation
         Answer: B) 2         
         
Explanation: Q is the son of R but R is not the mother. So, R is the Father of Q. P is married to R 
So, P is the wife of R and the mother of Q, X is the daughter of P and hence of R and so she is the Sister of Q, Y is the brother of R and Z is the brother of P. 
Clearly, Q is the son of P and X is the daughter of P. So, P has two children.
