Final answer:
The ability to grant the request from thread t1 for resources (0, 4, 2, 0) depends on the system's current resources, allocation state, and deadlock avoidance algorithm in use. More information is required to give a definitive answer.
Step-by-step explanation:
The question you've asked pertains to whether a request from thread t1 for resources (0, 4, 2, 0) can be granted immediately. This question appears to be related to concepts in operating systems, specifically to deadlock avoidance and resource allocation. The answer would depend on the current state of resource allocation and availability, along with the maximum demand of all threads. If the available resources can satisfy the demand of the pending request from t1 without causing a system deadlock, then the request can be granted. To answer this question with certainty, we would need more information, such as the current resource allocation matrix, the total amount of each resource in the system, and the maximum demand of each thread.
