{'family': [0, 1, 0, 0], 'father': [15, 3, 10, 14], 'children': [0, 0, 1, 0], 'brothers': [0, 1, 2, 1], 'members': [37, 11, 44, 71], 'doctor': [0, 1, 3, 2], 'adults': [0, 1, 0, 0], 'engineer': [0, 1, 1, 1], 'child': [5, 2, 2, 8], 'son': [0, 3, 0, 3], 'brother': [0, 2, 2, 2]}

From the given information, we can determine the relationships within the family as follows:

A and D are brothers.

A is a doctor.

E is married to one of the brothers (either A or D).

E and the brother she is married to have two children.

B is married to D.

G is the child of B and D.

Since A is a doctor and is a brother of D, and B is married to D, we can conclude that B is married to A. Therefore, E is married to D, and they have two children. This means C is one of the children of E and D.

Thus, C is A`s son.
