This is kind of an awkward situation.

A, B, and C are definitely false:

A ... gasoline is not a renewable resource

B ... hydroelectric dams don't use wind for anything; windmills do

C ... fossil fuels are not renewable resources

So that leaves D, but D is partly absurd too.

Natural gas burning does not produce gases to turn the turbines.  Natural gas is burned to produce HEAT, just like on the stove in my kitchen.  The heat is used to boil water, and the steam from the boiling water is what turns the turbines to generate electrical energy.

But I guess you gotta pick  choice-D  as the answer.

The answer is D. Natural gas can be burned, producing hot gases that turn turbines to generate electricity.
