The binding energy per nucleon is maximum in the case of

The energy in $MeV$ released due to the complete transformation of $1\, kg$ of mass into energy is $(c = 3 \times 10^8\, m/s)$:

Given below are two statements:
Statement $I$: For all elements, greater the mass of the nucleus, greater is the binding energy per nucleon.
Statement $II$: For all elements, nuclei with less binding energy per nucleon transform to nuclei with greater binding energy per nucleon.
In the light of the above statements, choose the correct answer from the options given below:

The binding energy per nucleon versus mass number curve for nuclei is shown in the figure. $W, X, Y$ and $Z$ are four nuclei indicated on the curve. The process that would release energy is

Calculate the energy equivalent of $1 \ g$ of substance.

If $M_o$ is the mass of an oxygen isotope $_8O^{17}$,$M_p$ and $M_N$ are the masses of a proton and a neutron respectively,the nuclear binding energy of the isotope is
