The source of power in a nuclear power plant comes from a) burning hydrogen atoms. b) reacting uranium atoms. c) splitting uranium nuclei. d) combining hydrogen nuclei.

C) splitting uranium nuclei

Explanation:

Nuclear energy is the energy that is obtained by manipulating the internal structure of atoms, usually useful to produce electricity.

This type of energy can be obtained by nuclear fusion and by nuclear fission:

So, the source of power in a nuclear power plant comes from splitting uranium nuclei, since when a nuclear fission (or a nuclear fusion) occurs, the atoms experience a slight loss of mass, which becomes a large amount of heat energy.

oh it is true if thats what you are asking
