Four of the following five are alike in a certain way and so form a group. Which is the one that does not belong to that group ?

A is wife of H and B is the wife of F, => A and B are females, while H and F are males.

A sits third to the left of E, => alternate positions are taken by males and females since no two males or two females are immediate neighbours of each other.

F sits second to the right of D, => D is also a male.

D is not an immediate neighbour of A or E, => D sits 2nd to the right of E and F sits to the immediate left of A. Thus, the remaining male position is taken by H, i.e. to the immediate right of A.

H and C are immediate neighbours of each other, => C sits between E and H.

F is not an immediate neighbour of his wife B, => B sits between E and D, thus G sits to the immediate right of D.

Among the given members, only G is a female.

=> Ans - (D)
