• B. Alphabetical and numerical.
• C. Graphical and tabular.
• D. Cause-effect and problem-solution.

Answer: (C)

Two common approaches to structuring a separate literature review are arranging sources chronologically or organizing them thematically. Chronological arrangement traces how ideas, methods, and findings have developed over time, helping you show progression, shifts in thinking, and the influence of early work on later studies. Thematic arrangement groups studies by shared topics, questions, or themes, which makes it easier to compare findings across different years, synthesize what is known about each topic, and identify gaps or debates within a domain. The choice depends on what you want to emphasize—the evolution of the field or the relationships among topics. Alphabetical or numerical ordering is mainly a reference tool for locating sources, not a narrative structure for synthesis. Graphical or tabular formats describe how you present information, not how you organize the literature itself. A cause–effect or problem–solution framing is another way to structure argument, but it isn’t the standard method for organizing multiple sources into a coherent synthesis.
