Final answer:
The last section to be written in a research report is typically the Conclusion, which summarizes the research findings and may offer recommendations. The correct option is c.
Step-by-step explanation:
The last thing that should be written in a research report is the Conclusion. This section of a research paper is meant to summarize the importance of the experimental findings, interpret results, and often provides a call to action or recommendations based on the research conducted.
Additionally, following the conclusion, one might find an appendix which includes supplementary material not central to the main text, but this is typically considered separate from the main report body.
Throughout the research report, particularly in the Results and Discussion sections, researchers present and interpret their findings using tools like tables and graphs to illustrate their data, avoiding any duplicate information.
Finally, a comprehensive References section lists all the sources cited in the report, whereas a bibliography may include additional reading materials for interested readers. The correct option is c.
