B sits second to the left of Z’s husband. No female is an immediate neighbor of B. D’s daughter sits second to the right of X. X is the sister of Y. X is not an immediate neighbor of Z’s husband. Only one person sits between A and X. Case-1 A is the father of Y. Z’s brother D sits to the immediate left to the Z’s mother. Only one person sits between Z’s mother and E. Only one person sits between Y and Z. Y is the mother of C. Y is not an immediate neighbor of E.
From above family tree CASE1 is cancelled out. CASE-2 is final arrangement
