2. **Hold and Wait**: A process holding at least one resource is waiting to acquire additional resources.
3. **No Preemption**: Resources cannot be forcibly removed from processes holding them.
4. **Circular Wait**: A set of processes are waiting for each other in a circular chain.
Step 2: Conclusion.
