The correct answer is A. Artemis wasn’t great to have around because she’s the one who brought death and disease everywhere.
Explanation:
In writing, formal tone uses formal language or technical vocabulary; prioritizes facts and objectivity over personal opinions; follows grammar and style conventions; and also, avoids the use of contractions, slangs or informal words. In the case of the sentence "Artemis wasn’t great to have around because she’s the one who brought death and disease everywhere" this is the sentence that should be revised for a more formal tone because this sentence includes contractions as in "wasn't" and "she's"; informal expression like "wasn't great to have around" and also is based on a personal opinion, which are features that belong exclusively to informal writing tone, not to formal tone.
