In a certain code language, A+B means 'A is the brother of B', AтИТB means 'A is the son of B', A├ЧB means 'A is the wife of B' and A├╖B means 'A is the father of B'. Based on the above, how is Q related to S if 'P - Q ├╖R├ЧS+TтА▓?

Translate each symbol into its blood relation and trace the chain from right to left or left to right. P - Q means P is son of Q; Q / R means Q is father of R; R x S means R is wife of S; S + T means S is brother of T.
Translate each symbol into its blood relation and trace the chain from right to left or left to right. P - Q means P is son of Q; Q / R means Q is father of R; R x S means R is wife of S; S + T means S is brother of T.
Analyze P - Q
P - Q means 'P is the son of Q'. Hence, Q is the parent of P.
Analyze Q / R
Q / R (given as division symbol meaning father) means 'Q is the father of R'. Thus Q is male and is the father of both P and R.
Analyze R x S
R x S means 'R is the wife of S'. This makes S the husband of R, and consequently the son-in-law of Q.
Determine Q's relation to S
Since Q is the father of R, and R is married to S, Q is the father of S's wife, which means Q is the Wife's father to S.
A: Husband's brother is incorrect as it refers to a brother-in-law of a female. C: Wife's brother is incorrect as R is female and married to S, making her husband's brother-in-law. D: Father is incorrect because Q is the father of R, making him the father-in-law of S (Wife's father), not S's direct father.
B is correct because Q is the father of R and R is the wife of S, making Q the wife's father to S.
Always convert coded relationship symbols into direct familial terms first, then construct a compact tree diagram from left to right or right to left based on the question's orientation.
