The classification is a process of dividing various objects various into ground on the bases of the properties common to them. The classification helps us to make a homogeneous group from the given heterogeneous group.
Classification means 'to assort the items' of a given group on the basis of a certain common quality they possess and then spot the stranger 'odd one out'.
We consider the defining quality of particular things. In these questions, four as five element or parts are given, out of which one does not belong to the group. You are required to find the 'odd one'.
There are following types of questions based on classification which we shall consider here.
(A) Non - verbal classification on the basis of position -
Solution : Except (C) are all lines have 2 arrow.
Solution : Except (E) are all doted lines opposite to each other.

Solution - There is a dark point in option (D).
(C) Classification on the basis of arms position -
Solution - In the option (B), there is the point is situated on the direct figure.
(D) Classification on the basis of clockwise figure rotation -
Solution - Anti clock wise (ACW) rotation in option (D).
(E) Classification on the basis of No. of figures -
Solution - There are same figure number inner and outer figures in option (E).
(F) Classification on the basis of figure relation -
Except (C) are remain have same diagrams have same element between middle and outer layer. Except (C) option are all having a miniature of outer layer.
