Explanation
According to the ServiceNow Hardware Asset Management overview document1, consumables are items that are used up or depleted over time, such as toner cartridges, batteries, or paper1.
According to the ServiceNow Product Documentation on Consumables2, when a consumable is requested and delivered, an asset record is created for it in the Consumable Asset [alm_consumable] table2.
According to the ServiceNow Knowledge Base article on How to Modify a Consumable asset record after it has been Consumed3, once an asset is consumed, it is gone from the world, and so nothing should need to do anything more with the Consumable Asset record3.
However, the article also states that the record is marked inactive but remains in the system, and that this should never need to be done3. This implies that the default behavior of the system is to keep the record in the system but mark it as inactive after it has been consumed3.
Therefore, the correct answer is A. The record is marked inactive but remains in the system.
