Correct answer: C
For a deadlock to occur, four specific conditions must hold simultaneously:
Mutual Exclusion (Non-shareable resources)
Hold and Wait
No Preemption
Circular Wait
No Preemption is the actual condition required for deadlock. If "Preemption" is allowed, the operating system can forcibly take a resource away from a process to give it to another, which actually helps prevent or break a deadlock.
