Solution

The correct option is A increases
The ionization energy, or ionization potential, is the energy required to completely remove an electron from a gaseous atom or ion. Ionization energies increase moving from left to right across a period (decreasing atomic radius). Ionization energy decreases moving down a group (increasing atomic radius).
