Answer:
I believe this is about Voltaire's story Micromegas. I believe B. would be the best answer.
Step-by-step explanation:
Micromegas was written from the viewpoint of an alien and his companion observing human society and making fun of it's self-centeredness. As the alien was 20,000 foot tall, I doubt if man would have been intimidating, or dignified for that matter. The two aliens were surprised by the warlike nature of humanity however, which makes option C a possibility. But when they were told that the universe was created for humanity's enjoyment, both aliens burst out in laughter, which is why I am going to go with B.
