Explanation

The tone of a sentence is the name given to the intonation and how an idea is expressed. the speaker separates his thoughts using pauses or silences and by variations in the tone of voice; in written language, these pauses and variations in pitch are generally represented by the period (.) and, sometimes, by question marks (?), exclamation points (!) or by an ellipsis (...). Additionally, the tone can be modified with the words used towards another person, for example, the sentence "Perhaps Anna could consider her decisions more carefully" invites Anna to reflect on her decision and make her decisions more carefully, unlike the sentence "Anna-she's a girl who acts silly" because she has a more aggressive tone towards Anna and makes a value judgment on the situation by insulting the other person. Therefore, the sentence that shows the best tone of the writer is A. Perhaps Anna could consider her decisions more carefully.
