Your Answer is
Correct Answer is J
Explanation
This question examines attributive clauses and pronouns. Here the attributive clause modifies personnel, and the subject is missing in the clause, so it is wrong to use who, G/H.
Whom can only be used as an object in a clause, because the subject of the clause is personnel, so the object of me cannot use the reflexive pronoun myself (the reflexive pronoun and the subject should refer to the same), item J is correct, and item F is wrong.
