Displaying statistically significant pairwise differences directly on the plotted results (Figure 2) with clear annotations and a short accompanying discussion is the best approach because it combines visual clarity with interpretive context.

1) Relevant knowledge points and concepts
- Effective communication of statistical results requires both visual presentation (to show magnitudes and trends) and annotation (to indicate which comparisons are statistically significant).
- Common visual annotations include asterisks, bracketed lines connecting groups, or letters indicating group-wise differences from post hoc tests.
- A brief textual discussion interprets the practical meaning, effect direction, and any caveats.

2) Step-by-step reasoning
- The goal is to let readers immediately see which group comparisons differ while also understanding the implication. A figure with significance annotations achieves this in one glance.
- A figure shows means/medians and variability (error bars), so annotating significant pairs overlays hypothesis-test results on the substantive data.
- The accompanying discussion should summarize which pairs are significant, refer to effect sizes or confidence intervals, and note the test used and alpha level.

3) Intermediate presentation considerations (no numerical calculation required)
- Annotate each significant pair on the graph (e.g., brackets with * for p<0.05, ** for p<0.01).
- Include a legend or caption explaining annotation conventions and the test/post-hoc method used.
- Keep the discussion concise: report direction, practical importance, and whether multiple comparison correction was applied.

4) Why option b is correct
- It integrates visual evidence and interpretive text, making results accessible and interpretable, which is the recommended best practice for a discussion section.

5) Why other options are less appropriate
- a) Table 3 and associated discussion: Tables are precise but less immediate; readers may not connect numeric differences to visual group patterns.
- c) Text-only discussion: Lacks a visual reference, making it harder for readers to assess magnitude and context.
- d) A new figure showing only difference and test statistic: Shows significance but omits raw group means/variability, reducing intuitive understanding.

Conclusion: Option b is the best choice, matching the provided answer.
