• C. A literature review surveys existing work, identifies gaps, builds theoretical framing, and informs the research question and methods; it situates the study within the scholarly conversation.
• D. It is a plan for data collection.

Answer: (C)

A literature review is a careful survey of existing work in a field that helps you see what is known, what isn’t, and how ideas connect. It identifies gaps, contradictions, and underexplored areas, which points you toward a precise, meaningful research question. It also helps build a theoretical or conceptual framing by showing which theories apply, how key concepts have been defined and measured, and what methods have been used successfully. Because of that, it informs the wording and scope of your research question and guides the choice of methods, data sources, and even study design, ensuring your project contributes to the scholarly conversation rather than duplicating what’s already done. It places your study in context, demonstrating relevance and originality.
