Which group shows the correct order of first ionization energy?

Ca > Na > K Al > Si > P K > Ca > Ge
Na > P > Cl
Cs < Rb < Na

I know the closer the element is to the right side of the table, group 8, the higher the ionization level, and the lower the group, the lower the ionization energy. What does it mean when it says "first ionization energy"
