While at first glance it may seem that A might be a plausible option, the section emphasizes the human struggle to keep a flame alive and the old process for how fire was procured.

Furthermore both answers B and D are also quite unlikely as they do not relate as much to the content at hand.
I would say c since he asked in the end sentence. <span> "And so I leave it with all of you: Which came out of the opened door - the lady, or the tiger?"</span>
