We’re being asked to rank the given elements by decreasing electron affinity


Recall that electron affinity is the energy change from the addition of 1 e to a gaseous element/ion


It is represented by this chemical equation:

Atom(g) + e  Ion(g), ΔE = –E.A. 


The trend for electron affinity is as follows: it increases from left to right and decreases down a period in the periodic table. The given elements are:
