Identify the reason for the gradual change in electronegativity in halogens down the group.
A. Electronegativity increases down the group due to decrease in atomic size
B. Electronegativity decreases down the group due to decrease in tendency to lose electrons
C. Electronegativity decreases down the group due to increase in atomic radius/ tendency to gain electron decreases
D. Electronegativity increases down the group due to increase in forces of attractions between nucleus & valence electrons
