B. The passage describes how the absence of human activity will change Central Park to show that nature will eventually destroy what people have built.

Explanation:

Alan Weisman's book "The World Without Us" presents an image of a world post-human existence where nature will blossom to its extreme capacity. This book delves into the environmental 'tortures' that humans have subjected nature.

The given passage is from the ending of Chapter 3 "The City Without Us" where the narrator talks of Central Park's "reincarna[tion] as marshes." Without the presence of humans, the busiest park in Manhattan has turned into a "maturing forest ... radiating down former streets and invading empty foundations." This supports the author's structure of presenting how a post-human world would look like.

Thus, the correct answer is option B.
