What is the primary action described by the word "dispel"?

The word "dispel" primarily refers to the action of causing something to disappear or go away, particularly in the context of ideas, doubts, or fears. When something is dispelled, it is often sent away or separated from one's mind or presence, which aligns with the notion of causing something to separate and go in different directions.

In this context, when we think of "dispel," it conjures images of dispelling clouds to allow sunlight to shine through, or dispelling fears to create a sense of clarity. This indicates movement away from something that was previously present. The other choices do not capture this essence of separation and dispersion in the same way.
