d) All of these

Final answer:

To ensure the circular wait condition never holds, one strategy is to a. impose a total ordering of all resource types and to require that resources be requested in a strict order.

Step-by-step explanation:

One way to ensure that the circular wait condition never holds is to impose a total ordering of all resource types, and to require that each process requests resources in an increasing order of enumeration. This means that a process can request resource type Rj only if it currently holds no resources or it holds resources Ri where i < j. This strategy prevents the circular wait condition by designing a strict order in which resources can be requested, and ensures that circular wait cannot form because there is no way to request a lower-ordered resource after acquiring a higher-ordered one.

The correct answer is d) All of these. One way to ensure that the circular wait condition never holds is by imposing a total ordering of all resource types and determining whether one precedes another in the ordering. This helps prevent deadlock by avoiding circular dependencies. Additionally, by never letting a process acquire resources that are held by other processes and letting a process wait for only one resource at a time, we can ensure that the circular wait condition does not occur.
