Sharing Spreadsheet

Version control keeps a history of changes to a shared file or project. Collaborators can identify revisions, compare versions, understand what changed, and restore an earlier version if an error occurs. It supports transparency and coordination; it is not designed to delete files, hide work, or increase incorrect information. Therefore, option A is correct.

A viewer can generally open and read the shared file without changing its contents. An editor can modify data, formulas, formatting, or other content, depending on the service’s permission settings. Because edits may introduce errors or remove information, edit access should be limited to people who need it and can be trusted; view access follows the principle of least privilege.

Access permissions determine what users can do with a shared folder, such as read, create, modify, or delete files. If students can edit when they should only view, the folder or account permissions need to be reviewed and corrected. Thus option A is correct. Mouse size, monitor brightness, and paper thickness do not control network access rights.

Edit permission allows a user to change the contents, so giving it to everyone creates an unnecessary risk of accidental or intentional alteration. The principle of least privilege says that each person should receive only the access needed for the task. Students who only need to read should receive view access, while editing should be limited to authorised contributors.

Edit permission allows a person to change the shared file, so giving it to everyone increases the chance of accidental or unauthorised changes. The safer principle is least privilege: provide editing only to people who need it and give others view access when possible. Renaming or deleting files does not correct the permission problem.

Edit permission allows a person to change the contents of a shared file. Giving it to everyone creates unnecessary opportunities for accidental or unauthorized changes. The principle of least privilege is safer: give edit access only to people who need it and give others view-only access. A shorter name or the Recycle Bin does not control permissions.

Access permissions determine whether a user can view, edit, create, or delete items in a shared folder. If students can edit when they should only read, the folder or their group membership may have been given excessive permission. Change it to view-only or read permission and test with an appropriate account. Mouse, display, and print settings do not grant editing rights.

Edit permission allows a person to change the contents, so it should be given only to members who need to modify the project. Other members can receive view or comment access if appropriate. Giving everyone full control increases the chance of accidental or unauthorised changes; an unnamed file or widely shared password does not solve the permission problem. Hence, B is correct.

Edit permission allows a person to change spreadsheet content, so giving it to every user increases the chance of accidental or unauthorised changes. Access should follow each member’s actual role; trusted contributors may edit while others can view or comment. A public control setting and sharing passwords reduce security, so B is correct.
