It’s C.
Pay attention to the grammar and punctuation.
Hooks also known as grabbers are sentences at the beginning of any argument essay or essay as a way to grab the attention of a reader. A grabber is only one sentence long and appears in the first paragraph in a argument essay/essay. So, in this case a hook for drugs and smoking would be something like.... "Did you know that drugs and smoking is one of the biggest addictive problems today?"
Hope this helps.
You can eliminate C because that is a Flat Character.
The answer is A from what I see.
