Question

where do charts get the data series names?
○ data entries
○ row labels
○ column labels
○ worksheet title

Explanation:

In spreadsheet software (like Excel), when creating a chart, the data series names are typically derived from the column labels. Column labels define the categories or series of data being plotted. Data entries are the actual values, row labels are for row - related categorization, and the worksheet title is not related to data series names for the chart. So the correct option is column labels.

Answer:

C. column labels
