Correct answer: B
Multitasking enables a single user to perform multiple tasks at one time by allowing the operating system to manage the execution of multiple processes or applications simultaneously.
How it works:
The operating system rapidly switches the CPU between tasks (context switching), giving the user the impression that tasks run at the same time.
Scheduling and time-slicing ensure each process receives CPU time in turn.
Example: a user can browse the web while music plays and files download in the background.
Types: preemptive multitasking (the OS interrupts tasks to switch) and cooperative multitasking (tasks yield control voluntarily).
