Worksheets and charts
Answer is Right!
Answer is Wrong!
The correct answer is: D. Worksheets and charts
An Excel workbook is a collection of worksheets and charts. A worksheet is a single page in a workbook, and a chart is a visual representation of data. Worksheets can be used to store and organize data, and charts can be used to visualize data and make it easier to understand.
Option A is incorrect because a workbook is a collection of worksheets, not other workbooks.
Option B is incorrect because a workbook is a collection of worksheets, not charts.
Option C is incorrect because a workbook is a collection of worksheets and charts, not just charts.
