Why Might the Following Nuclear Reaction Not Be Very Good

Multiple Choice

Why might the following nuclear reaction not be very good for energy production in a fusion reactor? Fe + Fe → Te

A) The material only produces a few neutrons so the chain reaction will not be very efficient.
B) The reactants are too stable and it would cost energy to produce the product due to strong nuclear force.
C) The products are not the right size to obtain any energy from the missing mass due to the strong nuclear force.
D) The mass of the byproducts is too high and therefore the energy released will not be high enough.
E) Interatomic attraction between the products will impede the separation of the atoms from the unstable nuclei.
