In a code, 'P $ Q' means 'P is the son of Q', 'P # Q' means 'P is the sister of Q' and 'P @ Q' means 'P is the mother of Q'. In the expression 'R @ S # T $ U', how is S related to U?
S is the daughter of U. S is the sister of T, so S is female, and T is the son of U. Siblings share the same parent, so S is also a child of U, which makes her U's daughter.

Explanation
S # T means S is the sister of T, so S is female. T $ U means T is the son of U, so U is a parent of T. S, as T's sister, is also a child of U, and being female she is U's daughter. 'Sister' would be wrong because T, not U, is S's sibling.
