Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Line chart with months on the x-axis and revenue on the y-axis
(Line chart) is correct because line charts are ideal for showing trends over time, such as monthly sales revenue over five years. Option B (Stacked bar chart) would segment each year, making it harder to see continuous trends. Option C (Scatter plot) is for relationships between two variables, not time series trends. Option D (Pie chart) is for proportions, not trends over time.

For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Line chart with months on the x-axis and revenue on the y-axis
Why this is correct
Line chart is best for displaying continuous data over time and highlighting trends.

Stacked bar chart showing each year as a segment
Why it's wrong here
Stacked bar chart is good for part-to-whole comparisons over time but less clear for overall trend.
- ✗
Scatter plot with revenue vs. month number
Why it's wrong here
Scatter plots show correlation between two variables, not a sequential trend.
- ✗
Pie chart for each year showing revenue distribution
Why it's wrong here
Pie charts are not designed for time series; they show proportions at a single point.
