To predict the approximate energy release of a nuclear reaction, we need to calculate the change in mass (∆m) during the reaction. We can use a table of nuclear masses, which lists the masses of all the isotopes and elements. The change in mass (∆m) is the difference between the mass of the reactants and the mass of the products.
Then, we can use the Einstein's famous equation E = ∆m * c^2, where c is the speed of light. This equation relates mass and energy, where a small amount of mass can release a huge amount of energy. 
Multiplying the change in mass by the speed of light squared will give us the energy released during the reaction. Thus, the best choice is B - find the change in mass and multiply by the speed of light squared.
