A Correct answer
Explanation

The atoms showing tendency to gain one or more electrons is said to be non-metallic. On moving down a group, the atomic radii of atoms increase. This results in less effective attraction from nucleus side for the electrons in the outermost shell. So, down the group, the tendency to lose electrons increases, while the tendency to gain electrons is reduced. Hence, the non-metallic character decreases as we go down a group.
