Answer:
D. Pleasing climate
Explanation:
One of the reasons that there are many amusement parks in Orlando, Florida is the city's pleasant climate. Amusement parks are usually outside, and good weather is necessary for people to visit them. If it were cold in Orlando, there wouldn't be many visitors, and the parks would close down. The same goes for the population - there would be way fewer visitors if the city had a small population. Interesting local wildlife has nothing to do with amusement parks. 
Thus, option D is the correct one.
