Answer:
C). Tension.
Step-by-step explanation:
A Gothic novel as the title itself demonstrates the mysterious characteristics by employing a setting that terrifies the audience. As per the question, the authors create 'tension' in the story to withhold or delay the revelation of information that keeps the interest of the readers intact until the end and leaves them uncertain about the action or horror coming up in the plot. This assists to evoke the desired response(terror, worry, horror) from the audience. It also includes conflicts that help build the tension in the plot. Thus, option C is the correct answer.
