The given electronic configurations are for elements $X$,$Y$,and $Z$. Note that these configurations represent ions of the elements:
$X = [Ne] \, 3s^2 \, 3p^5$
$Y = [Ne] \, 3s^2 \, 3p^6$
$Z = [Ne] \, 3s^2 \, 3p^4$
Determine the correct statement regarding the energy changes associated with these configurations.

• A
  Conversion from $Y$ to $X$ will require more energy compared to conversion from $X$ to $Z$.
• B
  Conversion $X \to Y$ and $X \to Z$ both are endothermic.
• C
  Both are correct.
• D
  None is correct.
