Research into nuclear fusion will likely require a large investment of time and money before it might be used as an energy source. which statement best describes the benefits that would make the investment worthwhile? a. fusion requires a large amount of energy and occurs in stars. b. fusion produces large amounts of energy, and the fuel is found on earth. c. fusion produces no radioactive waste, and the fuel is plentiful. d. fusion requires little energy to begin and would continue through a chain reaction.

C. Fusion produces no radioactive waste, and the fuel is plentiful.

Explanation:

Nuclear fusion occurs when two smaller nuclei combine together and fuse into a heaver nucleus. In the process, part of the mass of the original nuclei is converted into energy, according to the Einstein's famous equation:

and therefore a huge amount of energy is released in the process.

The simplest example of nuclear fusion is the fusion of two nuclei of hydrogen into a nucleus of helium. This is the process that occurs also in the core of the stars. Nuclear fusion does not produce any radioactive waste (contrary to the nuclear fission), and also, we have unlimited supplies of fuel on the Earth: in fact, the main fuel of the nuclear fusion is the hydrogen, which can be extracted from the water.
