Step 1: Understanding Active Voice:
In active voice, the subject performs the action. To change a sentence from passive voice to active voice, we need to adjust the word order and make the subject perform the verb directly.
Step 2: Analyzing the Options:
- Do they speak Hindi? This is the correct form in active voice. The subject "they" is performing the action of speaking Hindi.
- Speak Hindi will they? This is incorrect as it does not follow proper word order in English questions.
- Should they speak Hindi? This is a question asking for advice or permission and is not a correct conversion of the original passive sentence.
- Hindi must they speak? This is incorrect because it uses an unnatural word order for a question. The proper form is "Do they speak Hindi?"
Step 3: Conclusion:
The correct active voice sentence is Do they speak Hindi?.
