# For which of the following process energy is absorbed?

$\begin{array}{1 1}(a)\;\text{Separating an electron from an electron}\\(b)\;\text{Separating an electron from a proton}\\(c)\;\text{Separating a proton from a proton}\\(d)\;\text{Adding an electron into a neutral atom}\end{array}$

Energy is needed to overpower the forces of attractions among oppositely charged particles.
Hence (b) is the correct answer.
