Problem
Deuterium and tritium nuclei must be heated to extremely high temperatures before they can fuse mainly to overcome
(a) the large difference in their binding energies
(b) the short–range nature of the nuclear force
(c) the electrostatic repulsion between their positively charged nuclei
(d) the need to supply activation energy to break the nuclei apart before fusion occurs
