The correct option is:

Electronegativity decreases down a group, and reactivity increases down a group.

In metals, as you move down a group in the periodic table, electronegativity generally decreases, while reactivity tends to increase due to the increasing size of the atoms and the shielding effect that makes it easier for metals to lose their valence electrons.
