Answer. The adverb of the word beautiful is beautifully. The word beautifully means doing something in a graceful, attractive, or pleasant way. It follows the correct spelling and grammar rules. Thus, the correct answer is option B.
Complete Answer:
In English grammar, most adverbs are formed by adding -ly to adjectives. Since beautiful ends with -ful, we follow the same rule and add -ly to make beautifully. This word is used to describe how an action is done in a graceful, attractive, or pleasing manner.
For example, in the sentence She dances beautifully, the word beautifully tells us how she dances. It follows the standard rule of adjective-to-adverb formation, which makes beautifully the correct and grammatically appropriate choice among all the given options.
Analysis of other options:
While wheat is the correct answer, let us understand why the other options, Beautifuly, Beautifuler, and Beautifulest, are not suitable. Here are the reasons:
Option A: Beautifuly is not correct.
The word beautifuly is a spelling mistake. The correct spelling of the adverb is beautifully, with double l before -y. When we change the adjective beautiful to an adverb, we add -ly. Since beautiful ends in l, we keep both l letters before adding -y. That is why beautifuly is incorrect, it does not follow the correct spelling rule.
Option C: Beautifuler is not correct.
Beautifuler is not an adverb. It tries to be a comparative adjective, but the word beautiful does not form its comparative with -er. We say more beautiful, not beautifuler.
For example, we say,
Correct: This painting is more beautiful than that one.
Incorrect: This painting is beautifuler than that one.
Also, the question asks for an adverb, not a comparative adjective. Since beautifuler is not an adverb and does not describe how an action is done, this option is incorrect.
Option D: Beautifulest is not correct.
The word beautifulest is an incorrect attempt to form the superlative of beautiful. In standard English, we say most beautiful, not beautifulest.
For example, we say, She is the most beautiful girl in the class, and not She is the beautifulest girl in the class. Also, beautifulest is not an adverb. It does not describe the manner of doing an action. Since the question asks for an adverb, this option does not match the requirement.That is why option D is also wrong.
