Topic: Sentence (বাক্য),

Best Answer Explained in Below-:

In the question “_____ you from Barcelona?” the correct word to fill the blank is "Are". This is because the question is inquiring about the origin or place of residence of the person being addressed, which involves the verb "to be."

When asking about someone's identity or their roots, we use the form of "to be" that agrees with the subject. In this case, "you" is the subject, and the appropriate form of "to be" for "you" is "are." Thus, the complete question becomes "Are you from Barcelona?"

The other options do not fit grammatically or contextually:

- **A) Is**: This form is used with singular third-person subjects (he, she, it) and cannot be used with "you."
- **C) Do**: This auxiliary verb would require a different construction, such as "Do you come from Barcelona?" but that’s not the structure here.
- **D) Where**: This word is an interrogative adverb used to ask about location and cannot function as the verb in this question.

Therefore, "Are" is the only option that correctly forms a grammatically accurate and contextually relevant question.
