Best Answer Explained in Below-:

The question and answer pair requires the use of the verb "to be" in the correct form for both instances. The phrase "Where ______ she from?" asks about the origin of a female subject, in which case we need the singular form of the verb "to be" since "she" is a third-person singular pronoun. Therefore, the correct verb to fill in the blank is "is," making the complete question read: "Where is she from?"

In the response, "She ______ from Japan," we again refer to the same female subject, requiring the same third-person singular form of "to be." As such, the correct verb to fill in here is also "is," resulting in the complete answer: "She is from Japan."

The other options do not fit grammatically. Option A (are / is) would incorrectly use "are" for the singular subject "she". Option C (is / am) misuses "am," which is used only with the pronoun "I." Lastly, option D (are / are) incorrectly applies "are," which is used for plural subjects or with "you." Therefore, option B (is / is) is the only grammatically correct choice.
