Show answer & explanation

Correct answer: A

In coded blood-relation puzzles, decode each symbol into its stated relation first, then chain the relations together — tracking gender and generation at each link — to work out how the two named people are connected.

  1. R - V means R is the wife of V, so R is female and married to V.

  2. V x T means V is the brother of T, so V and T are siblings and V is male.

  3. T ÷ W means T is the daughter of W, so W is a parent of T.

  4. Since V is T's sibling and T is W's child, V is also W's child — and because V is male, V is the son of W.

  5. R is the wife of V, and V is the son of W, so R is the wife of W's son.

That makes R the daughter-in-law of W. Cross-check: W's children are T (daughter) and V (son); R, married to the son V, fits exactly the daughter-in-law relationship — confirming the answer.
