'A # B' means 'A is brother of B'.
'A @ B' means 'A is the daughter of B'.
'A & B' means 'A is the husband of B'.
'A % B' means 'A is the wife of B'.

If W%D#G@B&M@I, then how is D related to M?

  1. A
    Grandson
  2. B
    Grandfather
  3. C
    Father
  4. D
    Son

Solution & Step-by-step Explanation

Let's break down the relationships step-by-step from the given code expression:
W%D⟹ W is the wife of D (D is a male).

D#G⟹ D is the brother of G.

G@B⟹ G is the daughter of B. Since D is G's brother, D is the son of B.

B&M⟹ B is the husband of M (So, M is the mother of D and G).

M@I⟹ M is the daughter of I.

We need to find how D is related to M:
From step 4, we directly know that B is the husband of M, and D is their son. Therefore, D is the son of M.
