A. Hydrogen.
Deuterium actually slows the atomic reaction becuase it requires more energy to fuse due to its higher mass. Uranium fusion would create a particle so massive it would immediately self destruct and release an uncontrollable burst of energy, destroying the reactor. Alpha Particles won't fuse due to the fact that they all carry a positive charge, and thus repel each other.

B. Deuterium, or heavy hydrogen has an extra proton which is essential in starting a chain reaction to motivate the plasma to supercritical....more mass more momentum. Theoretically we would like to use hydrogen....but not feasible yet.
Look at the HBT-Tokamak.

Deuterium (the extra neutron is needed in the formation of Helium)

a) ordinary hydrogen.
I recall reading about cold fusion i think... although some say its mythical.... although others blame it for destroying a labratory.
