I think the answer is B because when you think of wind as an energy source you think of wind turbines,, the big things that turn high in the sky. And since it’s in the sky, birds and other flying animals can fly into it and die. Furthermore it can’t be A since wind energy doesn’t use radioactive material, for C I do not believe it uses ground water, and for D the small greenhouse gas emissions it may make to convert the wind energy into electricity (it might not produce any, it depends on how far science has come in the past few years) would be nothing compared to the amount produced burning coal or using gasoline or something like that.
