Mutual Exclusion is a condition when one or more than one resource are non-sharable (Only one process can use at a time) i.e. processes claim exclusive control of the resources they require. So, option (B) is correct.

Explanation:
Deadlock is a state in which two or more processes are waiting for each other to release resources, resulting in a standstill. There are four necessary conditions for deadlock to occur.
1. No preemption: Once a process is in possession of a resource, it cannot be taken away by another process. This condition ensures that a process can complete its task without interruption. However, it can lead to deadlock if a process is holding onto a resource while waiting for another resource.
2. Mutual exclusion: This condition ensures that a resource can only be used by one process at a time. This condition is necessary to maintain the integrity of the resource. However, it can lead to deadlock if a process is waiting for a resource that is being held by another process.
3. Circular wait: This condition occurs when a set of processes is waiting for each other in a circular chain. This condition can lead to deadlock if each process is holding onto a resource while waiting for another resource.
4. Hold and wait: This condition occurs when a process is holding onto a resource while waiting for another resource. This condition can lead to deadlock if multiple processes are holding onto resources while waiting for other resources.
Out of the four necessary conditions, mutual exclusion is the one that processes claim exclusive control of the resources they require. This means that a resource can only be used by one process at a time, which can lead to deadlock if a process is waiting for a resource that is being held by another process. Therefore, option B is the correct answer.
