Solution

The correct option is B decreases from left to right across a period and increases on descending a group
In the periodic table, the metallic character of element decreases from left to right across a period and increases on descending a group. The same order is of the atomic radius. Reverse order is true for ionization energy, electron affinity and electronegativity.
