In a certain code language,

A # B means ‘A is the son of B’,

A % B means ‘A is the brother of B’,

A − B means ‘A is the wife of B’,

A @ B means ‘A is the father of B’.

Based on the above, how is C related to K if ‘C # O − M % P @ K’?​​

Given: A # B means ‘A is the son of B’,

If ‘C # O − M % P @ K’?

So, C is father's brother's son of K.

Thus, correct option is (d).
