Consider the following policies for preventing deadlock in a system with mutually exclusive resources.
I. Processes should acquire all their resources at the beginning of execution. If any resource is not available, all resources acquired so far are released.
II. The resources are numbered uniquely, and processes are allowed to request for resources only in increasing resource numbers.
III. The resources are numbered uniquely, and processes are allowed to request for resources only in decreasing resource numbers.
IV. The resources are numbered uniquely. A process is allowed to request only for a resource with resource number larger
than its currently held resources.
II. The resources are numbered uniquely, and processes are allowed to request for resources only in increasing resource numbers.
III. The resources are numbered uniquely, and processes are allowed to request for resources only in decreasing resource numbers.
IV. The resources are numbered uniquely. A process is allowed to request only for a resource with resource number larger
than its currently held resources.
- a)Any one of I and III but not II or IV
- b)Any one of I, III and IV but not II
- c)Any one of II and III but not I or IV
- d)Any one of I, II, III and IV
Correct answer is option 'D'. Can you explain this answer?

Understanding Deadlock Prevention Policies
In computer systems, deadlock occurs when two or more processes are unable to proceed because each is waiting for the other to release a resource. The policies listed aim to prevent such situations.
Policy I: All Resources at Start
- Processes must acquire all resources at the beginning.
- If any resource is unavailable, all previously acquired resources are released.
- This approach can prevent deadlock but may lead to inefficient resource utilization.
Policy II: Increasing Resource Requests
- Resources are uniquely numbered.
- Processes can request resources only in increasing order.
- This prevents circular wait conditions, thereby eliminating the potential for deadlock.
Policy III: Decreasing Resource Requests
- Similar to Policy II but allows requests in decreasing order.
- This also prevents circular waits and avoids deadlock.
Policy IV: Larger Resource Requests
- Processes can request a resource only if its number is larger than any currently held resources.
- This strategy prevents deadlocks by ensuring that processes do not hold resources while waiting for lower-numbered resources.
Conclusion: Why Option D is Correct
- All four policies (I, II, III, and IV) are valid methods of preventing deadlock:
- Policy I enforces resource acquisition discipline.
- Policies II and III prevent circular waits through ordered requests.
- Policy IV ensures that held resources do not block future requests.
Therefore, the correct answer is option 'D': Any one of I, II, III, and IV can effectively prevent deadlock in a system with mutually exclusive resources.

If Ist is followed, then hold and wait will never happen. II, III and IV are similar. If any of these is followed, cyclic wait will not be possible.
