Which statement about nuclear fusion is correct? a. two hydrogen electrons become protons during fusion. b. helium nuclei can fuse to form elements such as nitrogen. c. the fusion reaction lasts for several hundred years. d. large nuclei break apart to form smaller nuclei.

C. The fusion reaction lasts for several hundred years.

Explanation:

Nuclear fusion is a nuclear reaction whereby two smaller nuclei come or fuse together to form a large or heavier nuclei.

Nuclear fusion is a reaction that occurs very well in the sun. It is means by which the sun generates light and heat.

Whenever nuclear fusion occurs, a large amount of energy is always released.

During nuclear fusion, there is the coming together of hydrogen atoms via proton to proton chain reaction and this leads to the formation of Helium.
