Correct answer & explanation
✓
Waterfall chart
A waterfall chart shows how an initial value is affected by a series of positive and negative changes, making it ideal for financial breakdowns.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Line chart
Why it's wrong here
A line chart connects data points to show trend over a continuous axis; it cannot decompose net income into revenue, cost and expense contributions. It is tempting for time-series financial trends, and would be correct if the analyst needed to show how a single measure changed across periods.
- ✗
Area chart
Why it's wrong here
An area chart plots cumulative magnitude over a continuous axis, so individual revenue, cost and expense contributions to net income are obscured by stacking. It is tempting for showing trends of totals over time, and would be correct if the analyst needed to display cumulative volume across a period.
- ✓
Waterfall chart
Why this is correct
A waterfall chart models cumulative addition and subtraction, starting at revenue and stepping through costs and expenses to arrive at net income. Each bar isolates one component's contribution, directly satisfying the requirement to show how net income is derived and to highlight each component's individual effect.
- ✗
Pie chart
Why it's wrong here
A pie chart displays parts of a whole at a single point in time, but the question requires showing how net income is derived from revenue, costs, and expenses *over a period*. A pie chart cannot depict changes across time or the sequential subtraction of costs and expenses from revenue. It is tempting because it effectively highlights each component’s proportional contribution in a static snapshot, which would be correct if the analyst only needed a single-period breakdown of net income’s composition.
