(a) choose the correct answer.
stacked area chart
pie chart

Explanation:

(a)

The problem is about identifying the type of chart. A stacked area chart is used to show how parts contribute to a whole over time or across categories, and since the graphic is about median earnings by education (categories) over time (implied by the context of earnings over years), and the options include stacked area chart (pie chart is for proportions of a whole, not trends over categories/years here). So the correct option is the stacked area chart.

Answer:

A. Stacked area chart
