Show answer & explanation
Correct answer: D
A multi-programmed operating system is defined by keeping multiple programs in main memory simultaneously to maximize CPU utilization. When one program waits for an event or terminates, the OS immediately schedules another ready program to ensure continuous processing. Therefore, all three statements accurately describe the core features of a multi-programmed OS.
