The correct answer is B. Radiated
Step-by-step explanation:
In texts including narrative text and literary texts, the tone refers to the attitude shown by the author in the text and that can be described as joyful, sad, humorous, sarcastic, indifferent, critical, etc. Additionally, the tone depends on other elements such as the setting, descriptive details and the words used.
In the case of the sentence "The red roses radiated with color like a morning sunrise" the tone of this can be classified as positive or joyful, because the author states "The red roses radiated" that implies the author feels positive toward the roses and because of this the author thinks the roses have a beautiful glow. Because of this, in this case, the tone is determined by the word "radiated" and therefore this is the word that needs to be replaced from changing the tone, which includes modifying it to make it neutral.
