To effectively convey percentages of a whole, a pie chart is generally the most recommended method of data presentation. Pie charts visually represent data as slices of a circle, where each slice corresponds to a category's proportion of the total. This method allows the audience to quickly grasp the relative sizes of different categories in terms of their percentage contributions to the whole.

While other methods like bar graphs can also show parts of a whole, they are typically better suited for comparing quantities rather than displaying parts-to-whole relationships. Infographics might include pie charts but are more about overall storytelling or information summarization. Normal distribution, on the other hand, is a specific statistical concept that is not designed for presenting percentages of parts to a whole.

In summary, for showing percentages of a whole, the best choice is A pie chart.
