Answer:

D) energy required to remove a valence electron

Explanation:

Ionization energy can be defined as the atom's ability to and the energy required to remove a valence electron. Ionization energy increases up a group and to the right along a period. So helium has the highest first Ionization energy meaning that it is very hard to remove an electron from helium because octet is already complete.
