A. Nuclear fusion involves the splitting of a nucleus; nuclear fission involves combining two or more nuclei.
False: Nuclear fusion involves combining two or more nuclei and nuclear fission involves the splitting of a nucleus.
B. Reactors for nuclear fusion are much more realistic than are reactors for nuclear fission.
False: both the reactors are realistic.
C. Nuclear fusion produces much more energy than nuclear fission.
True: the energy of fusion is more than the energy of nuclear fission.
D. Nuclear fusion requires a enough fissionable material present to create and sustain a chain reaction
False: Nuclear fission requires a enough fissionable material present to create and sustain a chain reaction.
