Which three options are correct about application workbooks?

The statement that worksheets can be modified by using the Cube Designer wizard is valid. The Cube Designer wizard serves as a powerful tool within Oracle Analytics that allows users to create, manage, and modify cube structures and their associated worksheets. This mechanism enhances the capability to manipulate data and provides a user-friendly interface for adjustments, streamlining the overall data analysis process.

In terms of the other options, while they might contain elements that could lead to consideration, they do not accurately represent the functions or features associated with application workbooks in the context of Oracle Analytics. Therefore, the emphasis on the Cube Designer wizard's role demonstrates its importance in modifying worksheets effectively within application workbooks.
