In a certain code, 'P @ Q' means 'P is the father of Q', 'P % Q' means 'P is the wife of Q' and 'P & Q' means 'P is the brother of Q'. In the expression 'M @ N & O', how is M related to O?
M is the father of O. M is the father of N, and N is the brother of O, so N and O are siblings. A father of one sibling is the father of the other as well.

- CBrother
- DGrandfather
Explanation
M @ N means M is the father of N. N & O means N is the brother of O, so N and O are siblings. M, being the father of N, is also the father of O. Uncle is wrong because M is a parent of N, not a sibling of O's parent.
