B is the son-in-law of D, E is the daughter of D, and is not married to B. F is the daughter of G. Daughter of B sits on the immediate left of G who faces E. B has no brother: Brother-in-law of G sits second to the right of B. Father-in-law of A and B faces same direction. Father of E does not sit in the same square with his son-in-law. So, the blood relation tree

Brother-in-law of G sits second to the right of B and both faces opposite direction, Father of E does not sit in the same square with his son-in-law. No one sits on the immediate right of B.

So, the blood relation tree

There is only one vacant seat in each square. The vacant seats are not in front of each other. Daughter of B sits on the immediate left of G, who faces E. E does not sit in the same square with F.

Father-in-law of A and B faces same direction. D is not the immediate neighbour of G. Fand.A face same direction. F does not face vacant seat. So, case 2 and Case 4 is eliminated.

E and F faces same direction. B and F does not face each other. So, case 3 will be eliminated.
