Which of the following is a benefit of using nuclear power?

A) Using nuclear power requires greater use of fossil fuels.

B) Core meltdown of reactors can provide "bonus" energy for electricity production.

C) Few greenhouse gases are emitted.

D) Mining activities enhance ecosystems.

E) The increasing costs of non-renewable energy sources make nuclear energy more economically viable.

Option (E)

Explanation:

Nuclear energy is directly obtained from the elements that are radioactive in nature. The use of nuclear energy doesn't emit any greenhouse gas and there is no burning of fossil fuels. In order to extract the non-renewable resources from a particular area, a huge amount of money is required to carry out the entire process.

So in comparison to that, nuclear energy is much efficient to use but there is a problem with the disposal of the waste materials that are released in the mines. This is harmful as there is continuous emission of radiation releasing from these wastes.

Nuclear energy is therefore carried out at a relatively isolated place away from the human settlement areas and is quite workable in comparison to the non-renewable sources of energy.

Thus, the correct answer is option (E).
