✅ Option d — Adjacent bar chart
All Options:
- AHistogram
- BPie chart
- COgive
- DAdjacent bar chart
Detailed Solution & Explanation
Let us analyze the data and choose the most suitable diagram:
1. **Data characteristics**: There are two entities (sales-persons) whose weekly sales performance needs to be compared side-by-side for each week over a month (4 weeks).
2. **Adjacent Bar Chart**: Also known as a multiple or grouped bar chart, this diagram places bars representing different categories (the two sales-persons) side-by-side (adjacent) for each time period (each week). This allows for direct visual comparison of their weekly sales.
3. **Other options**:
- **Histogram**: Used for continuous frequency distributions, not for comparing individual performance over time.
- **Pie chart**: Used to show the component-wise breakdown of a single total, not for comparing weekly trends of two entities.
- **Ogive**: A cumulative frequency curve, used to find medians or quartiles, not for comparing weekly sales.
Therefore, an adjacent bar chart is the most appropriate diagram.
Hence, **Option D** is the correct answer.
