Solution

The correct option is B $C l$
Electron affinity is defined as the change in energy of a neutral atom when an electron is added to the atom to form a negative ion, i.e., an atom gains the electron. Electron affinity decreases down the group but $C l$ has more affinity than $F$ because of the smaller size of fluorine.
