If I want to compare the proportionate (percentage) contribution
of two variables with multiple components to each variable, which
chart type should I use?

Place Order

A. Scatter Diagram

B. Bar chart

C. Stacked bar chart

D. 100% Component bar chart

E. Pie Chart

I think it’s a stacked bar chart, but I’m not completely sure.
Can you tell me why I’m wrong or right?
