Final answer:
The correct answer is option b) Not deadlocks. Unsafe states indicate an inconsistent state in a system where resources may be used incorrectly or unpredictably, but they do not always lead to deadlocks.
Step-by-step explanation:
The correct answer to the question is option b) Not deadlocks. All unsafe states are not deadlocks. Deadlocks occur when two or more processes are unable to proceed because each is waiting for the other to release a resource. Unsafe states, on the other hand, may or may not lead to deadlocks, but they indicate that a system is in an inconsistent state where resources may be used incorrectly or unpredictably. Therefore, the answer to the question is not deadlocks.
