Explanation
The option that supports this requirement is B. To restrict users' access to export reports, the administrator can remove the "Export Reports" user permission from their profile or permission set. The "Report Manager" user permission is not related to exporting reports, but to creating and managing report folders.

Explanation
The error occurred because the trigger handler class is using ''with sharing'' and the user does not have access to the orders related to the opportunity. The ''with sharing'' keyword enforces the sharing rules that apply to the current user. This means that if the user does not have access to a record, they will get a permission error when trying to create or update it1. The trigger should use ''without sharing'' keyword instead, which ignores the sharing rules that apply to the current user. The trigger should not use RunAs(), IsCreateable(), or no sharing keywords as they will not prevent the error from occurring.

Explanation
Removing the Work Order Edit permission from the sales representative profile is the optimal approach to implement these requirements, as it will prevent sales representatives from changing virtual container work orders that are provisioned immediately by the system. Option B is incorrect, since removing the edit button from the work order page layout would not prevent sales representatives from editing work orders using other methods, such as inline editing or data loader. Option C is incorrect, since changing the record type/page layout assignment for Work Order to be Read Only would not affect the edit permission, but only the layout configuration. Option D is incorrect, since implementing a sharing rule that changes access for all Work Order to Read would not prevent sales representatives from editing work orders that they own.

Explanation
The two settings that are available in profiles, but not permission sets are C and D. Page layout assignments and login hours are profile-specific settings that control the user interface and the time range that users can log in to Salesforce. The other options are either available in both profiles and permission sets, or not related to either.
