C. A process is the smallest unit of resource allocation, and a thread is the smallest unit of CPU time allocation.

This statement is correct. A process is a container that holds the resources needed for a program to run, including memory, files, and devices. A thread is a unit of execution within a process that can run independently and share resources with other threads. CPU time is allocated to threads, not processes, making threads the smallest unit of CPU time allocation. Option A is incorrect because processes and threads are distinct concepts. Option B is incorrect as a process can exist without a thread. Option D is not the correct answer as option C is correct
