Answer:
A. is the answer
Explanation:
The hammer in the first position is raised and ready to hit the nail on the head. This is called potential energy. It has a lot of energy stored inside of it but it won't get used until we allow it to hit the nail. That is why it is not kinetic energy but only potential. Think of it just as when we say something has the potential to do something.
In urban areas, there are more people, therefore not a lot of farmland. (that eliminates C) If city buildings don't allow flood waters to recede, that could be dangerous in many ways. (So A is still a reasonable answer) If most cities are built in flood zones, there should be some form of shelter if houses aren't safe. Pollutants and diseases being carried in water are already dangerous, but easier to spread with rapid flood waters that are sweeping everywhere. So your best answer would be either A or B.
