If m, mn and mp are the masses of ZXAZX^{A}nucleus, neutron and proton respectively.

A

m<(A−Z)mn+Zmpm < (A - Z)_{m_{n}} + Zm_{p}

B

m=(A−Z)mn+Zmpm = (A - Z)m_{n} + Zm_{p}

C

m=(A−Z)mp+Zmnm = (A - Z)m_{p} + Zm_{n}

D

m>(A−Z)mn+Zmpm > (A - Z)m_{n} + Zm_{p}

Answer

m<(A−Z)mn+Zmpm < (A - Z)_{m_{n}} + Zm_{p}

Explanation

Solution

The mass of nucleus formed is always less than the sum of the masses of the constituent protons and neutrons i.e. m<(A−Z)mn+zmpm < (A - Z)m_{n} + zm_{p}.
