Question

Change the sentence “They have completed the work” into an interrogative sentence.

• A. Do they completed the work?
• B. Have they completed the work?
• C. Did they completes the work?
• D. Did they completed the work?

Hint:

In present perfect interrogatives, place \textit{have/has} before the subject without changing the past participle form.

Answer 1

The Correct Option is B

Concept: In present perfect tense, the auxiliary verb \textit{have/has} is placed before the subject to form a question. Explanation: The sentence is in present perfect tense (“have completed”). To convert it into interrogative form, we invert the auxiliary verb and subject. Thus, the correct sentence is: Have they completed the work?
