(C) Energy is released in a nuclear process if the total binding energy of the products is greater than the total binding energy of the reactants.From the graph:For $Z$: Mass number $A = 30$,$BE/A = 5.0 	ext{ MeV}$For $Y$: Mass number $A = 60$,$BE/A = 8.5 	ext{ MeV}$For $X$: Mass number $A = 90$,$BE/A = 8.0 	ext{ MeV}$For $W$: Mass number $A = 120$,$BE/A = 7.5 	ext{ MeV}$Let's evaluate option $(c)$: $W 	o 2Y$Total $BE$ of reactant $W = 120 	imes 7.5 = 900 	ext{ MeV}$Total $BE$ of products $2Y = 2 	imes (60 	imes 8.5) = 2 	imes 510 = 1020 	ext{ MeV}$Since the total $BE$ of the products $(1020 	ext{ MeV})$ is greater than the total $BE$ of the reactant $(900 	ext{ MeV})$,energy is released in this process.

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:
