The passage makes a general claim (nature lovers are drawn to forests and parks) and backs it up with one piece of everyday evidence: a lot of people visit Corbett park. Notice the shape of this reasoning: it states a general rule, then points to a single observed instance as proof, without checking whether that instance actually confirms the rule (visiting a park does not by itself prove someone is a "nature lover", there could be other reasons to visit).
Option C reproduces the same reasoning pattern as the original argument: a general belief supported by a single everyday observation, with no check on alternative explanations.
Let's summarize:
So the answer is option C.
