Solution & Step-by-step Explanation
When converting an interrogative sentence beginning with "Who" in the present perfect tense into passive voice:
1. "Who" changes to "By whom".
2. The auxiliary verb is adjusted based on the object ("the work", which is singular), so we use "has".
3. The structure follows: By whom + has + object + been + past participle ().
Thus, it becomes "By whom has the work been done?".
