Explanation:

This is a pretty interesting question. The author says “renewable energy can be produced at the household or neighbourhood level...but such small scale localised production is unlikely to generate high returns for investors.” This is a double edged sword. 2 goes out because efficiency has not at all been discussed in the last paragraph. Corporate control is indeed discussed but not in reference to democratic distribution of energy. Thus 3 goes out. 1 goes out because renewable energy has been discussed as a single idea, without any forms and types. Thus 1 also is a distortion

Hence, option (d) is correct.
