RRB Group D 2025 Question Paper (18-Aug-2026) (Shift 1)
The correct answer is

Wife's sister

Fb # Ki means Fb is the daughter of Ki, so Fb is female and Ki is her parent.

Ki × Tn means Ki is the wife of Tn, so Ki is the mother and Tn is the father of Fb.

Tn % Ec means Tn is the father of Ec, so Ec is a sibling of Fb.

Ec × Yt means Ec is the wife of Yt, which makes Ec female (Fb's sister) and Yt her husband.

Hence, Fb is the wife's sister of Yt.
