There are 3 resources R1, R2 and R3 with one instance each and three processes P1, P2 and P3 in an operating system.  A snapshot of the system resource allocation graph shows the following: R1 is allocated to P2; R2 is allocated to P1; R3 is allocated to P3; P1 requests R1; P2 requests R3; P3 requests R2.  Which of the following is true about this system? answer ) a)Undetermined b)There is deadlock in the system c)Deadlock will never happen d)There is no deadlock in the system
