A system with three processes has three resource types. The system has three processes (P1.P2, P3) and three resources (R1,R2, R3). This is one instance of R1 and R2. There are three instances of R3.P1 holds R1 and is requesting an R3. P2 holds an R3 and is requesting R1. P3 holds two instances of R3 and an R2. Obtain a resource allocation graph for your own reference for answering the questions below. a. Is the system deadlocked? b. If not deadlocked, give the sequence in which the processes execute and finish. O a. not deadlocked, b. P1, P2, P3 O a. not deadlocked, b. P3, P1, P2 O a. deadlocked, b. not applicable O a. not deadlocked, b. P3, P2, P1
