The clerk will wait on whom is next is the proper sentence. Who is only used when it is the subject of a verb.
The clerk will wait on whoever is next.
A.who
Yes, a clerk should take each person in order. Take the first person and then after you have finished with them take the next in line.
Both "whom" and "whomever" work, depending on whether you want a specific person or any person at all. A good trick is to ask if you would use "he" or "him" in its place. "Who" goes with "he," and "whom" goes with "him." You can remember that by associating the words that have an "m" at the end together. (If you are talking about a woman or a girl, you should still use this trick, as "her" does not end with an "m," making it a bit harder to remember which goes with which.)
An admissions clerk checks all verifications needed for applicant to advance to the next level of entry.
The correct interrogative pronoun is who. (Who is next?)The pronoun 'who' functions as a subject in a sentence.The pronoun 'whom' functions as an object in a sentence.
The next after whom?
