Solution

The correct option is B Electronegativity
The sequence $F > C l > B r > I$ holds good for electronegativity.
On moving down the group of halogens, the electronegativity values decreases with decrease in non metallic character and increase in metallic character.
Boiling point and atomic size increase in the order $F < C l < B r < I$ on moving down the group of halogens.
On moving down the group of halogens, the electron affinity order is $C l > F > B r > I$ .
