The tallest blue segment (representing Democrats) shows a higher percentage of opposition to the law compared to the red segment (representing Republicans). Therefore, a greater percentage of Democrats oppose the law compared to Republicans. Option A and B are incorrect because the red segments are taller than the yellow segments for both Democrats and Independents respectively. Option C is incorrect because the chart clearly shows that political party affiliation is associated with the opinion on the law. Option E is incorrect because a segmented bar chart is a suitable way to present this type of categorical data.
