4. In a Resource Allocation Graph, there are three processes A, B, and C and three types of resources R1, R2 and R3. Resource R1 has 4 instances, R2 has 3 instances and R3 has 2 instances respectively. Process A holding a resource R1, R2 and requesting for resource R3. Process B holding resources R2 and R3 and requesting for resource R1. Process C holding a resource R2, R3 and requesting for resource R1. (A) Draw the Resource Allocation Graph in the space provided below. (5.5 Marks) (B) Based on the above graph what is the condition of the processes and resources? (1) Tick the correct condition.
