Which of the following is not a standard permission level in Sitecore?

In Sitecore, standard permission levels are categorized based on common actions that can be performed on items. Read, Edit, and Delete are all established permission levels that correspond to specific capabilities within the Sitecore platform.

• Read permissions allow a user to view the content items without making changes.

• Edit permissions enable a user to modify the content of items, allowing for updates and changes.

• Delete permissions grant a user the ability to remove items from the content tree.

On the other hand, "Modify" is not recognized as a standard permission level within Sitecore's permission structure. This term suggests a broader capability that might imply editing or changing items but does not exist as a discrete permission setting in Sitecore. Standard permissions are designed to be clear and specific to reduce confusion about what actions a user may perform. Therefore, among the listed options, "Modify" stands out as the one that does not fit into the established permission categories within Sitecore.
