The correct answer is B. Data series.

To identify the patterns used for each data series in a chart, you need to understand what a data series is. A data series represents a group of data points that are plotted on a chart. It could be a set of values for a specific category, such as monthly sales figures for different products or the temperature readings for different cities over a period of time.

To determine the patterns used for each data series in a chart, follow these steps:

1. Identify the chart you are working with. This could be a bar chart, line chart, pie chart, etc.

2. Look for the various data series displayed on the chart. Each data series is usually represented by a different color or pattern.

3. Examine the chart legend, which is a key that explains the colors or patterns used in the chart. The legend provides information on which data series each color or pattern represents.

4. Match the colors or patterns in the legend to the corresponding parts of the chart. This will help you identify the patterns used for each data series.

In summary, to identify the patterns used for each data series in a chart, you need to review the chart legend and understand how the colors or patterns correspond to the data series displayed on the chart.
