Answer: Option B

In questions, 'do' or 'does' usually starts the sentence, but it doesn’t have to. For a simple interrogative sentence, or question, 'do' or 'does' is typically followed by the subject, and then the conjugated verb.
Questions with 'do' or 'does' as the first word usually elicit a 'yes' or 'no' answer. If the question starts with 'who, what, where, when,' or 'why,' the word 'do' or 'does' can come after that question word.
