Quizplus · Accepted Answer

The system has 4 resources and each process needs a maximum of 2 units. So, the total number of units needed by all the processes is 2 * 3 = 6 units. Since the system has 4 resources, there is no way that all the processes can get the resources they need at the same time. Therefore, deadlock can never occur.
