Functions of review of literature – UGC NET Question

Here statements A, C, D and F correctly present the role of review of literature, while B and E are wrong. Statement A is true because reviewing existing work prevents unnecessary duplication. Statement C is correct since literature review supports the choice of theoretical framework, and statement D is right that it may suggest tools and designs. Statement F is also true as prior studies help interpret current findings, whereas B is false because review is not restricted to the final stage and E is false because even experts require systematic review to stay updated.

Option A:
Option A labels only B as wrong, but statement E is also incorrect. Although B wrongly postpones literature review to after report writing, E wrongly claims that experts can skip review. Since both B and E misrepresent good practice, this option does not capture the full set of wrong statements.

Option B:
Option B singles out E as wrong but fails to include B. While E is indeed false, B is equally problematic in suggesting an inappropriate timing for the review. Because the option ignores one of the wrong statements, it is incomplete.

Option C:
Option C incorrectly adds F to the list of wrong statements. Statement F is in fact correct because prior studies provide a reference for interpreting current results. Grouping F with B and E misclassifies a true statement as wrong and makes the option invalid.

Option D:
Option D properly identifies B and E as the only wrong statements and leaves A, C, D and F untouched as correct. It reflects that review is needed before and during research and that expertise does not remove the need for systematic review. Therefore this combination is the correct answer.
