Answer:
A. This reminds me of reading about Caesar's assassination in history class.
Explanation:
The given excerpt actually connects to the reader by reminding the reader about the assassination of Julius Caesar. His assassination is usually taught in history classes. 
Caesar was actually assassinated by a group of senators; about 40 Roman senators assasinated him and stabbed about 23 times. 
The main motive behind his assassination was due to his tyrany and his plan to overthrow the Senate.
 
        
             
        
        
        
By putting it as a matter-of-fact statement (assuming everything else was action packed) there is a massive shift that creates contrast in the piece and leaves a very concise point to shock/leave the reader with.
