Final answer:

As halogen atoms increase in size, electronegativity decreases down the Group, leading to less attraction for electrons.


Explanation:

Electronegativity decreases down the Group of halogens as the atoms get larger, resulting in less attraction for electrons. This leads to a decrease in electronegativity and an increase in atomic radius down the group. Hence, the statement 'Electronegativity decreases and color deepens' best represents the trend in physical properties of halogens as the Group is descended.
