The correct answer is A. 4312.
The first word, “perfectly”, is an adverb that means “in a way that is without any faults or mistakes”. The second word, “right”, is an adjective that means “correct or true”. The third word, “is”, is a verb that means “to exist or be present”. The fourth word, “she”, is a pronoun that refers to a female person.
The sentence “perfectly right is she” can be interpreted in a few different ways. One interpretation is that the sentence is a statement of fact, meaning that the person referred to by “she” is perfectly right. Another interpretation is that the sentence is a question, meaning that the speaker is asking whether the person referred to by “she” is perfectly right. A third interpretation is that the sentence is a command, meaning that the speaker is ordering the person referred to by “she” to be perfectly right.
The first option, A. 4312, is the correct answer because it is the only option that forms a grammatically correct sentence. The second option, B. 2314, is not a grammatically correct sentence because the word “right” is not in the correct place. The third option, C. 4321, is not a grammatically correct sentence because the word “is” is not in the correct place. The fourth option, D. 2143, is not a grammatically correct sentence because the word “she” is not in the correct place.
