M_p denotes the mass of a proton and M_n that of a neutron. A given nucleus, of binding energy B, contains Z protons and N neutrons. The mass M (N, Z) of the nucleus is given by (c is the velocity of light)

A
M(N, Z) = NM_n + ZM_p–Bc²

B
M(N, Z) = NM_n + ZM_p+Bc²

C
M(N, Z) = NM_n + ZM_p–B/c²

D
M(N, Z) = NM_n + ZM_p+B/c²
