Suggested answer: A, C

Explanation:

Stacked bar charts will usually have lesser number of bars compared to a normal bar chart:

Normal bar chart - 9 bars

Stacked Bar Chart - 3 bars

We can easily see a 'part-of-a-whole' methodology being used here as well - we are seeing the breakdown of Segments within each Category.

To easily visualize trends over time -This is the definition of a line chart.

To visualize each discrete category using a separate bar -This can be accomplished using a simple bar chart, why use a stacked one?
