Well the chance of a hurricanes or tsunami damaging your city or house is greater. Another is that the soil closer to the coast can be a lot more moist, but that's not true for all places.
It would be C. Rain. Water is evaporated from the earth into the sky to form clouds. Then it turns into rain that falls to the ground, and this process continues.
I hope this helped if you need a better explanation then ask, and I'll see if I can't provide you with one.
