Statement Breakdown
Multiprocessing always requires multiple CPUs. — Incorrect

Multiprocessing requires multiple processing units (cores), which can easily exist on a single physical CPU chip (e.g., a modern multi-core processor like a quad-core or octa-core CPU).

Multitasking and multiprocessing are identical concepts. — Incorrect

Multitasking refers to a system executing multiple tasks/processes concurrently by rapidly switching between them (time-sharing).

Multiprocessing refers to the hardware capability of executing multiple threads or processes simultaneously using multiple processing cores/CPUs.

A single CPU can appear to run multiple tasks through time-sharing. — Correct

By allocating tiny slices of time (time-slicing) to different programs and switching between them quickly, a single processor core creates the illusion that all programs are running simultaneously.

Modern operating systems support multitasking. — Correct

Virtually all modern operating systems (such as Windows, macOS, Linux, Android, and iOS) natively support preemptive multitasking.
