Two shared resources R1 and R2 are used by processes P1 and P2. Each process has a certain priority for accessing each resource. Let Tij denote the priority of Pi for accessing Rj. A process Pi can snatch a resource Rh from process Pj if Tik is greater than Tjk.
Given the following :
- T11>T21
- T12>T22
- T11<T21
- T12<T22
Which of the following conditions ensures that P1 and P2 can never deadlock?
- (I) and (IV)
- (II) and (III)
- (I) and (II)
- None of the above
