Explanation

The word “Please” functions as a verb and is commonly used to express a request or to convey politeness. However, when looking for its noun form, we assess the related words derived from the root. Among the given options, “Pleasure” (option B) stands out as the correct noun form associated with “Please.”

“Pleasure” refers to a state of satisfaction or joy that arises from fulfilling a desire or experiencing something enjoyable. It captures the essence of the feeling that comes when someone is pleased. For instance, when someone says, “It gives me pleasure to help,” it directly ties back to the sense of enjoyment associated with the act of pleasing others.

On the other hand, the other options“Pleased,” “Pleasing,” and “Pleaseness”do not function as direct noun forms of “Please.” “Pleased” is an adjective indicating a state of being happy or satisfied, “Pleasing” is an adjective that describes something that brings pleasure, and “Pleaseness” is not a commonly recognized word in standard English usage. Hence, “Pleasure” is the most appropriate and grammatically correct noun form derived from “Please.”
