Best Answer Explained in Below-:

The question asks for the verb form related to the noun "ability." The term "ability" refers to the capacity or power to do something, whereas its associated verb form is "enable." To enable means to make something possible or to provide the means for someone to do something, thus directly relating to the concept of giving someone the ability to perform an action.

Let's briefly look at the other options: "Able" is an adjective that describes someone who has the ability, while "ably" is an adverb that describes doing something in a competent manner. "Ability," as mentioned, is a noun. None of these options function as a verb. Therefore, "enable" is the only correct answer as it inherently relates to the act of facilitating or empowering others to achieve their capabilities, embodying the essence of what "ability" signifies. In summary, "enable" effectively captures the action associated with the potential expressed in "ability," making it the appropriate verb choice.
