Which of the following is correct for the electron affinity of halogens?

Identify the correct order of electron gain enthalpy (electron affinity) for the elements $Be, B, C, N$.

The electron affinity values (in $kJ \ mol^{-1}$) for halogens $X, Y,$ and $Z$ are $-349, -333,$ and $-325$ respectively. Therefore,$X, Y,$ and $Z$ are respectively which of the following?
