Answer:
A). Suspension of disbelief.
Step-by-step explanation:
The term "Willing Suspension of disbelief" was coined by the romantic poet and critic Samuel Taylor Coleridge. It suggests the loss or sacrifice of reason or logic for the sake of pleasure and enjoyment and such imagination would add fluency of thoughts without any concern about reason or logic. Similarly, Calvin in the given example keeps the logic and reason on one side and indulges himself in enjoying the science fiction and believe in the surreal images portrayed. Thus, option A is the correct answer.
