The correct option is B Nuclear energy
Nuclear fission of radioactive elements in small amounts generates an enormous amount of heat energy than a windmill, or a tidal or a geothermal power plant. Nuclear energy is used to produce electricity in a more economical and sustainable way, as long as it is put to good use. Whereas, tidal, wind, and geothermal energy yield a lesser energy output, though they are easier and safer to harness.
