MHT CET 2024 16th May Morning Shift | Atoms and Nuclei Question 3 | Physics

In $\mathrm{M}_{\mathrm{O}}$ is the mass of an oxygen isotope ${ }_8 \mathrm{O}^{17}$ and $\mathrm{M}_{\mathrm{p}}$ and $\mathrm{M}_{\mathrm{N}}$ are the mass of proton and mass of neutron respectively, then the nucleus binding energy of the isotope is

$\mathrm{M}_{\mathrm{o}} \mathrm{C}^2$

$\left(\mathrm{M}_{\mathrm{o}}-8 \mathrm{M}_{\mathrm{P}}\right) \mathrm{C}^2$

$\mathrm{\left(M_o-17 M_N\right) C^2}$

$\left(\mathrm{M}_{\mathrm{o}}-8 \mathrm{M}_{\mathrm{P}}-9 \mathrm{M}_{\mathrm{N}}\right) \mathrm{C}^2$
