Classification and odd-one-out – UGC NET Question

Statements A, B, C and E correctly describe the logic behind classification questions. Such items ask for the outlier, use a clear basis such as number properties or meaning, rely on a single consistent rule for the odd item and are best solved by first identifying what the majority have in common. Statement D is false because well-designed questions typically have exactly one odd item, not two, so that there is a unique correct answer. Hence, the combination that includes A, B, C and E but excludes D is the correct one.

Option A:
Option A is correct since it contains all of the true statements and omits D, which introduces ambiguity by suggesting two odd items. This option best reflects how classification questions are set in UGC NET and similar exams.

Option B:
Option B is incomplete because it omits E, failing to highlight the crucial strategy of first spotting the common feature shared by most items. Without E, the guidance on how to approach such questions is not fully conveyed.

Option C:
Option C is incorrect as it leaves out A and therefore does not explicitly mention that the task is to identify the non-member of the group, which is the central idea of classification items. Even though B, C and E are true, the set is not complete.

Option D:
Option D is wrong because it includes D, the false claim about having two odd items, and omits B, which correctly indicates different possible bases of grouping. By combining a wrong statement with omissions, this option cannot be accepted.
