Based on Their Relative Positions in the Periodic Table, Which

Based on their relative positions in the periodic table, which might you expect to be a stronger oxidizing agent, chlorine or fluorine? Why?

A) Chlorine should behave as a stronger oxidizing agent because it has a smaller effective nuclear charge in its outermost shell.
B) Fluorine should behave as a stronger oxidizing agent because it has a smaller effective nuclear charge in its outermost shell.
C) Chlorine should behave as a stronger oxidizing agent because it has a greater effective nuclear charge in its outermost shell.
D) Fluorine should behave as a stronger oxidizing agent because it has a greater effective nuclear charge in its outermost shell.
