Final answer:
Terminating a process will terminate all of its threads, as threads exist within the context of the process and share its resources.
Step-by-step explanation:
The termination of the process terminates c) All threads within the process. In the context of operating systems and computer science, a process is composed of one or more threads that execute within the process's context. When a process terminates, all of its constituent threads are also terminated since they share the process's resources and execution context. Any resources used by the process, such as file handles and memory allocations, are cleaned up and reclaimed by the operating system upon process termination.
