Final answer:
A new workspace generally starts as a blank slate and does not include any workbooks by default; it is meant for setting up according to a new project's requirements.
Step-by-step explanation:
When creating a new workspace in many software applications, particularly those related to coding or development environments, the behavior of what is included might depend on the specific software in question. However, assuming general cases, the ideal answer is usually D) None of the above. When you create a new workspace, it typically starts as a blank canvas, intended for you to set it up as per your project's needs. This means it would not automatically include the active workbook, all open workbooks, or workbooks from the previous session. Instead, you would typically import or create new files as necessary for the new project you are working on.
