The use of the reflexive pronoun "myself" is incorrect in this sentence, as it has no previous first person pronoun to refer to. The simple first person objective pronoun is the pronoun that needs to be used in this sentence. Thus, the correct answer choice is "was finally delivered to me."

The use of the reflexive pronoun "myself" in the sentence is incorrect, as it has no previous first person pronoun to refer back to. The regular first person pronoun is absolutely fine in this sentence. Therefore, the correct answer choice is "given to me before anyone else."

The use of the reflexive pronoun "myself" in this sentence is incorrect, as it has no previous first person pronoun to refer back to. The pronoun can be changed to the simple first person objective pronoun, "me." The only answer choice to make this necessary change is "please bring them back to me."

The use of the reflexive pronoun "myself" is incorrect in this sentence, as it has no previous first person pronoun to refer back to. The reflexive pronoun can be changed to the simple first person objective pronoun, "me." Therefore, the correct answer choice is "The packages could only be signed for by me."

The use of the reflexive pronoun "myself" in this sentence is incorrect and confusing, as it has no previous first person pronoun to refer back to. The reflexive pronoun can be changed to the simple first person objective pronoun "me" without changing the meaning of the sentence. Therefore, the correct answer choice is "Every single paper written by an employee must be given to me."

The use of the reflexive pronoun "myself" is incorrect in this sentence, as it has no previous first person pronoun to refer back to. The reflexive pronoun can easily be replaced by the simple first person objective pronoun, "me." The only answer choice that actually does this is "was only ever seen by me."

The use of the pronoun "myself" is incorrect in this sentence, as "myself" is a reflexive pronoun and needs a referent earlier in the sentence. As no earlier use of a first person pronoun exists in the sentence, a reflexive pronoun is inappropriate. "To me" is the correct answer choice. "To I" might look like a potentially correct answer, but because "I" is the object of the preposition "to," it needs to be in its objective form, "me," not its subjective form, "I."

The use of the pronoun "themselves" is incorrect in the sentence, as "themselves" is a reflexive pronoun and needs a noun earlier in the sentence to refer back to as a referent. This is the only issue in the sentence, and replacing "themselves" with the non-reflexive third person plural object pronoun "them" is sufficient. The correct answer choice, then, is "to them as soon as."

The use of "for me" is a confusing and odd use of the pronoun. Normally, we might consider changing "for me" to "for myself," since "I" has already been used in the sentence and "myself" would have a clear antecedent. However, the phrase "for myself" isn't necessary in this sentence; the sentence still makes complete sense without the inclusion of the phrase. Omitting the underlined portion simplifies the sentence and is grammatically correct, and it is the only answer choice that both corrects the error contained in "for me" and doesn't introduce other grammatical errors.

The use of the reflexive pronoun "herself" in this sentence is incorrect and confusing, as no third-person female pronoun or name has been mentioned, so "herself" has no antecedent. The sentence only needs to use the simple female third-person objective pronoun "her." Therefore, the correct answer choice is "to her immediately, with no delays."
