Disable an Application for a Group of Users

D.

The correct answer is D. Profiles.

Profiles are used to control the level of access that users have to objects and fields within an organization. They are used to determine which users have access to certain features, data, and functions within Salesforce.

To disable an application for a group of users, a system administrator would need to modify the profile assigned to those users. The administrator can remove access to the application from the profile by removing it from the profile's app permissions.

To modify a profile, the system administrator can follow these steps:

1. Click on the gear icon in the top-right corner of the screen and select Setup.
2. In the Quick Find box, type "Profiles" and click on the Profiles option.
3. Select the profile that needs to be modified.
4. Click on the "App Permissions" section and uncheck the box next to the application that needs to be disabled.
5. Click the "Save" button.

By removing the application from the profile's app permissions, the system administrator can effectively disable the application for all users assigned to that profile.
