Options:

Answer:

Solution:

When a nucleus is formed, then the mass of nucleus is slightly less than the sum of the mass of $Z$ protons and $N$ neutrons.
That difference in energy also known as binding energy needs to be supplied to nucleus to break it into respective number of protons and neutrons.

$M < (Z m_{p} + N m_{n})$
