The correct answer is A. To customize the maintenance routine for a specific computer or set of computers.
Explanation
A specific maintenance plan is a series of actions that allow an object to be properly maintained, allowing the user to customize the maintenance according to their interests, focusing mainly on details or special characteristics. This maintenance plan is more effective than automatic maintenance because automatic maintenance does not pay attention to details but only works on the generalities of an object. Therefore, the correct answer is A. To customize the maintenance routine for a specific computer or set of computers.
