* Permission sets control access to objects (such as pages, tables, reports) in Business Central. By creating a new permission set that specifically excludes the critical table (or page) and assigning this permission set to the users in Department A, you can prevent them from accessing the page.
* Option A (creating a different role center page) is incorrect because role centers control the user interface, but do not directly restrict access to specific pages or tables.
* Option B and Option C (extending the base application permission set) are not the best options because extending permission sets typically involves adding permissions, not removing access. The question requires restricting access to a critical page, so simply including or excluding permission sets won't solve the issue at the table or page level.
* Option D (creating an entitlement object) is not relevant here, as entitlements are used in more complex licensing scenarios or environments.
Summary:
Creating a permission set object that specifically excludes access to the critical table or page and assigning it to the users will solve the problem effectively.
