If “A ! B means, A is the son of B”, “A * B means, A is the wife of B”, “A % B means A is the brother of B”, “A § B means A is the mother of B”, “A £ B means A is the father of B”, then which of the following can be correct conclusion drawn from the expression ‘D £ Y % Z * C ! U § X’?

Option 4 : U is the mother in law of Z.

From the given expression ‘‘D£Y%Z*C!U§X’’, we get:

D£ Y means D is the father of Y,

Y%Z means Y is the brother of Z,

Z*C means Z is the wife of C,

C!U means Cis the son of U,

U § X means U is the mother of X.

Thus, using the following notations, we can draw the family tree:
