Final answer:
An Exclusive resource is the correct answer as it can only be used by one process at a time and isn't depleted by use, distinguishing it from nonrenewable resources.
Step-by-step explanation:
A Exclusive resource is one that can be safely used by only one process at a time and is not depleted by that use. This is in contrast to a nonrenewable resource, which is a natural resource that exists in a fixed amount and cannot be replenished quickly enough to keep pace with human use of the resource. An exclusive resource in computing ensures that when one process is using a given resource, no other process can access it until the first process has finished using it, preventing potential conflicts and data corruption.
