Which elements of worksheet can be protected from accidental modification A. Contents B. Objects C. Scenarios D. All of above

The correct answer is: All of above.

• Contents refers to the data in the cells of a worksheet.
• Objects refers to any graphical elements that have been inserted into a worksheet, such as charts, pictures, and shapes.
• Scenarios refers to a set of values that can be applied to a worksheet to see how the results change.

All of these elements can be protected from accidental modification by using the Protect Sheet command on the Review tab. This command allows you to specify which elements of the worksheet can be modified, and who has permission to make changes.

For example, you could protect the contents of a worksheet so that only you can make changes, while allowing others to view the data. Or, you could protect a scenario so that it cannot be changed without your permission.

Protecting a worksheet is a great way to prevent accidental changes and to ensure that your data is accurate.
