F (male) is A's father → So, A is the child of F.
C is A's daughter → So, A is C's parent (A can be male or female, but it doesn't affect the uncle relation).
G is the brother of C → So, A is also G's parent.
K is the sister of F → So, K is A's aunt (father's sister).
Finding G’s Uncle:
A's paternal uncle (father's brother) would be F’s brother, if mentioned.
However, no brother of F is given, only a sister (K).
If A has a maternal uncle, he would be A's mother's brother, but no such person is mentioned.
Final Answer:
Since no uncle (father’s or mother’s brother) is explicitly mentioned, the uncle of G is not determinable from the given information.
