A mass difference and Einstein's equation $E=m{c}^2$ are combined together to calculate an element's $$

decay constant

binding energy

nuclear density

activity

Which one of the following is the correct formula for nuclear binding energy?

$BE=[Z{m}_p-N{m}_n-M_N]c^2$

$BE=[Z{m}_p+N{m}_n+M_N]c^2$

$BE=\frac{(Z{m}_p+N{m}_n)-M_N}{c^2}$

$BE=[(Z{m}_p+N{m}_n)-M_N]c^2$
