Answer:
A). Style involves word choice; tone involves the impression your message makes.
Explanation:
Style is demonstrated as the literary component that demonstrates the author's writing style which is reflected through employment of words, structure, syntax, rhetorical language in his/her text to create the desired effect like mood or atmosphere to elicit desired response while tone is demonstrated as the author's approach towards a particular subject matter that offers a framework/lenses to the audience to perceive the text in a contextual and comprehensive manner. Therefore, option A best elucidates the difference between the style and tone as it correctly describes that 'style involves word-choice' that is associated with author's use of language and syntax while the 'tone makes the impression created by message' through the framework proposed by the author. Thus, option A is the correct answer.
