  1. A

    M(A,Z)=ZMp+(A−Z)Mn−BE/c2M(A, Z)=Z M_p+(A-Z) M_n-\mathrm{BE} / c^2M(A,Z)=ZMp​+(A−Z)Mn​−BE/c2

  2. B

    M(A,Z)=ZMp+(A−Z)Mn+BEM(A, Z)=Z M_p+(A-Z) M_n+\mathrm{BE}M(A,Z)=ZMp​+(A−Z)Mn​+BE

  3. C

    M(A,Z)=ZMp+(A−Z)Mn−BEM(A, Z)=Z M_p+(A-Z) M_n-B EM(A,Z)=ZMp​+(A−Z)Mn​−BE

  4. D

    M(A,Z)=ZMpP+(A−Z)Mnn+BE/c2M(A, Z)=Z M_p^P+(A-Z) M_n^n+B E / c^2M(A,Z)=ZMpP​+(A−Z)Mnn​+BE/c2
