What actions can be taken when creating new worksheets in a workbook?

When creating new worksheets in a workbook, the primary actions available include creating new worksheets or adding copies of existing ones. This flexibility allows users to expand their workbooks in a way that best suits their planning and analysis needs. By creating new worksheets, users can organize their data around different themes, projects, or time periods, enabling better management of information. Additionally, the ability to copy existing worksheets makes it easy to replicate formats or data structures without having to start from scratch, thereby increasing efficiency and consistency across the workbook.

The other options do not accurately reflect the capabilities associated with worksheet management. For instance, solely linking to worksheets from other workbooks would limit the functionality of data manipulation. Mixing and matching data from different platforms could complicate data integration and analysis without a clear framework. Lastly, restricting actions to only modifying existing worksheets would reduce the versatility that users require when working on comprehensive projects.
