Break the expression into individual relations and map them step-by-step from the target T towards M: T is wife of R, R is brother of Y, Y is son of G, G is father of M.
T × R
T is the wife of R (T is female).
R - Y
R is the brother of Y (R and Y are siblings).
Y + G
Y is the son of G (G is parent of Y and R).
G ÷ M
G is the father of M (M is the sibling of R and Y).
Conclusion
Since T is the wife of R, and R is M's brother, T is M's sister-in-law.
B: The relation 'Brother's wife' is equivalent to 'Sister-in-law'. C: T belongs to the same generation as M's brother, not the parent's generation. D: T is the wife of a brother, not the sister of M.
B is correct because T is the wife of R, and R is the brother of M, making T the wife of M's brother (Sister-in-law).
