Which is the noun of the word “Beautiful”? ?

The correct answer to the question "Which is the noun of the word 'Beautiful'?" is B) Beauty.

To understand this, it is essential to recognize the grammatical forms of the words in question. "Beautiful" is an adjective, which describes qualities or states of a noun, indicating that something possesses beauty or is pleasing to the senses. In contrast, a noun refers to a person, place, thing, or idea.

The word "beauty" directly refers to the quality or state of being beautiful, making it the noun form of the adjective "beautiful." For example, we can say, "The beauty of the landscape was breathtaking," where "beauty" acts as the subject of the sentence.

Option A, "Beautious," is an archaic or poetic adjective and does not serve as a noun. Option C, "Beautifully," is an adverb that describes how an action is performed, while option D, "Beautify," is a verb that means to make something beautiful. Therefore, none of these options serve as a noun equivalent for "beautiful," reinforcing that "beauty" is indeed the correct answer.
