Solution

The correct option is C $C I > F > B r > I$
Electron affinity is the amount of energy released when an electron is added to isolated gaseous atom. Electron affinity decreases down the group.
The electron affinity of fluorine is less than chlorine due to its smaller size.

So the correct order for electron affinity is $C I > F > B r > I$ .

Hence, the correct option is $B$
