What is the main benefit of separating user mode from kernel mode?

Answer and explanation

Correct answer: Protect critical system parts from application errors

The governing concept is privilege separation. Programs normally run in user mode with restricted permissions, while the kernel runs in privileged mode and controls sensitive memory, devices, and system operations. If an application crashes or behaves incorrectly, these limits help prevent damage to the whole system. Hence option B is correct. Full hardware control would weaken safety, and storage capacity or display resolution is unrelated.
