Which of the following sentences is most acceptable regarding grammar, spelling, and punctuation?

The first sentence is the most acceptable regarding grammar, spelling, and punctuation because it adheres to standard English language rules. It correctly uses commas to separate clauses, which helps clarify the meaning and maintain the sentence flow. The sentence effectively communicates that the firefighter has two distinct tasks: to keep a copy for herself and to share copies with the two other victims.

Additionally, "herself" is used correctly as a reflexive pronoun that matches the subject, and the phrase "the other two victims" is accurately structured with the appropriate adjective and numeral. This clarity and proper structure are essential in written communication, especially in professional contexts such as firefighting, where precision is critical for understanding roles and responsibilities.
