The CPU improves its performance through the implementation of one or more __________, which is made up of one or more __________.

• A. CPUs, fetches
• B. processes, threads
• C. cores, execute operations
• D. states, tasks

Answer: (B)

Understanding how processes and threads relate helps here. A running program is a process, and each process can contain one or more threads—the smallest units of execution that the CPU can schedule. When a program uses multiple threads, the CPU can switch between them, potentially running them in parallel on separate cores or overlapping computation with I/O. That makes the statement fit: a process is made up of threads. The other options don’t describe this standard relationship—cores are hardware units that execute operations rather than being built from them, and terms like fetches, states, or tasks don’t capture the same hierarchical link between a process and its threads.
