Answer: B)
Explanation:
The correct question should be ''Who is responsible for watching the little children...?'' because in that case 'Who' will be the most appropriate solution.
If we put Which or Whom it would be like the previous text of the question is missing and with Who this question is complete. If we leave it with Whoever is would be like the rest of question is missing.
This is the definition
archaic past and past participle of work.
I would say that the answer is probably 3. Hope this helped!
