Answer: I believe the answer must be D.
Explanation: Because wind is a renewable energy source as it can appear and disappear in general and it happens a lot within coastal areas! It's definitely needed! Solar panels cannot really float and it would be unusual for that to happen if I am being honest. Fossil fuels are not renewable and they take a lot of years for them to decompose and they cause lots of pollution. I'm not sure about C, but I don't find the answer to be correct because I feel it best for nuclear energy to be most appropriate in places with nuclear equipment like labs or factories. This is my best guess and I hope you get this right!!
I hope this helped you, but please double-check with your teacher on this question! Good Luck!! :)
