Answer
Brief Explanations:
Parallel structure requires consistent grammatical form. In the correct sentence, all clauses start with "who can" maintaining parallelism. The first option has a mix - "who can" and "who can" and then a different structure. The second option has "who wants", "who can" and "if you will" which is not parallel. The fourth option has "who can", "who can" and "which of us wants" which is not parallel.
Answer:
The boss wants to know who can take the late shift tonight, who can open tomorrow morning, and who can work on the holiday.
