The data handling options available during a CSV import—Add, Update, or Add or Update—are directly controlled by the permission levels assigned to the user's role for the specific record type being imported. If a user's only available option is "Add," it signifies that their role has the "Create" permission for that record type but lacks the "Edit" permission. The "Create" permission allows for the creation of new records, which corresponds to the "Add" data handling function.

A. If the role had the "Edit" level permission, the "Update" data handling option would also be available to the user.
B. The "Import CSV File" permission grants access to the import tool itself; its level (e.g., Full) affects saving mappings, not the data handling options for a specific record type.
D. The "Import CSV File" permission level does not dictate the data handling options; the permissions on the target record type are what govern this setting.

Reference Point: In the section "Step 2 Import Options," the documentation details the "Data Handling" field, clarifying that the ability to select "Add," "Update," or "Add or Update" is contingent on having Create, Edit, or both permissions, respectively, for the record type.
