Which of the following is most suitable for representing part-to-whole relationships?HistogramScatter plotPie chartLine chart

To determine the most suitable type of chart for representing part-to-whole relationships among the given options, let's evaluate each choice:

1. Histogram: This type of chart is used to represent the distribution of numerical data and is not designed to show part-to-whole relationships.

2. Scatter Plot: A scatter plot shows the relationship between two quantitative variables. It's useful for identifying correlations but does not effectively illustrate part-to-whole relationships.

3. Pie Chart: Pie charts are specifically designed to display part-to-whole relationships. They represent data as proportions of a whole, visually showing how different segments contribute to the total.

4. Line Chart: Line charts are used to track changes over time and show trends rather than part-to-whole relationships.

Conclusion

Given this analysis, the most suitable option for representing part-to-whole relationships is the Pie Chart. It effectively conveys how different components make up a total, making it the ideal choice for this purpose.
