I say this but I didn't read the passage, so excuse me if I'm wrong. It doesn't seem to be A, sense it isn't contrasting a statement. It really could be C as well, but this seems to be something it would focus on. It could not be D because it is not a concluding sentence, it would leave the passage in an awkward state. This is why I say B.

There is extraneous information in the diagram. There is duplicate information where you have... There are rivers flowing beneath our feet... a myth? Can stay because it’s simplified. The information ...Have you ever heard that there are rivers of water flowing underground? Do you think it’s true? should be deleted because it’s duplicating the simplified statement prior. Also, Some rivers, such as the Alpaha River in northern Florida, USA,can disappear underground during low flow periods isn’t relevant to the rest of the diagram. Generally water underground is more like water in a sponge is inaccurate and should be deleted. It states in the diagram later on that the water underground is a filler between the rock particles and soil. I hope this helped you. Sorry I didn’t see it sooner.
