Answer:
D). Overly charged language.
Step-by-step explanation:
In an argumentative essay, the author adopts a formal style and language tone in order to establish his/her sincere depiction of the topic. It is clearly reflected through the precise use of vocabulary to communicate his/her idea that allows the readers to form an uninfluenced opinion or conclusion about the topic.
When an author wishes to maintain a formal style, he/she must replace the 'overly charged language' with a 'clear and specific language.' The charged language reflects the author's personal opinion or emotions associated with the topic which degrades the author's respect and unbiasedness as it tries to persuade them. Thus, option D is the correct answer.
