What is a safe state in deadlock avoidance?
What is a safe state in deadlock avoidance?
Show Hint
Look for the option about an ordering that lets every process finish.
Updated On: Jul 2, 2026
- A state where no processes are currently using resources
- A state where processes must request resources in a specific sequence
- A state where the system can allocate resources to all processes in some order without leading to deadlock
- A state where at least one process is currently blocked

The Correct Option is C
Solution and Explanation
Step 1: Deadlock avoidance checks whether granting a resource request keeps the system in a state from which every process can still finish.
Step 2: A state is called safe if there exists at least one ordering of the processes, a safe sequence, such that each process can get all the resources it needs and complete.
Step 3: If such an order exists, the system can hand out resources without ever getting stuck, so deadlock is avoided.
Step 4: Option (C) captures exactly this. Being idle, following a fixed request order, or having a blocked process do not define a safe state. The answer is (C).
