Both metals and non-metals are found among.... elements in the periodic table

In the plot of the first ionization energy against atomic number the peaks are occupied by:

Which of the following orders for electron affinity is/are correct-

(a) $\mathrm{S}>\mathrm{O}<\mathrm{Se}$

(b) $\mathrm{Cl}>\mathrm{F}$

(c) $\mathrm{S}>\mathrm{O}$

(d) $\mathrm{O}>\mathrm{S}$
