To "preclude" means to:

The term "preclude" derives from the Latin root that means to shut off or prevent. When something is described as being precluded, it indicates that it cannot occur because a certain condition or action prevents it from happening. This aligns perfectly with the definition of making something impossible or preventing it from taking place.

In contrast, the other options suggest positive actions or outcomes. "Enable and allow" would imply facilitating a situation, while "encourage and promote" suggests providing support or motivation for something to happen. "Invite and include" refers to welcoming participation, which is the opposite of prevention. Thus, the correct interpretation of "preclude" focuses on the aspect of prevention, solidifying option B as the accurate choice.
