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.
  • 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?
