In a system, there are three types of resources: E, F and G. Four processes P0, P1, P2 and P3 execute concurrently. At the outset, the processes have declared their maximum resource requirements using a matrix named Max as given below. For example, Max[P2, F] is the maximum number of instances of F that P2 would require. The number of instances of the resources allocated to the various processes at any given state is given by a matrix named Allocation. Consider a state of the system with the Allocation matrix as shown below, and in which 3 instances of E and 3 instances of F are the only resources available.
From the perspective of deadlock avoidance, which one of the following is true?
  • a)
    The system is in safe state
  • b)
    The system is not in safe state, but would be safe if one more instance of E were available
  • c)
    The system is not in safe state, but would be safe if one more instance of F were available
  • d)
    The system is not in safe state, but would be safe if one more instance of G were available
Correct answer is option 'A'. Can you explain this answer?

Available (3, 3, 0), which can satisfy either P0 or P2. Take P0 <3, 3, 0>.
After completion we have (3, 3, 0) + (1, 0, 1) = (4, 3, 1) Take P2 <0, 3, 0>.
After completion we have (4, 3, 1) + (1, 0, 3) = (5, 3, 4) Take P1 <1, 0, 2>.
After completion we have (5, 3, 4) + (1, 1, 2) = (6, 4, 6) Take P3 <3, 4, 1>.
After completion we have (6, 4, 6) + (2, 0, 0) = (8, 4, 6)
Safe sequence : P0→P2→P1→P3 Therefore, option (A) is Correct.
