Which series is correctly arranged in order of decreasing radius?

A.     \({\text{A}}{{\text{l}}^{3 + }} > {\text{M}}{{\text{g}}^{2 + }} > {\text{N}}{{\text{a}}^ + } > {{\text{F}}^ - }\)

B.     \({{\text{F}}^ - } > {\text{N}}{{\text{a}}^ + } > {\text{M}}{{\text{g}}^{2 + }} > {\text{A}}{{\text{l}}^{3 + }}\)

C.     \({{\text{F}}^ - } > {\text{A}}{{\text{l}}^{3 + }} > {\text{M}}{{\text{g}}^{2 + }} > {\text{N}}{{\text{a}}^ + }\)

D.     \({\text{N}}{{\text{a}}^ + } > {\text{M}}{{\text{g}}^{2 + }} > {\text{A}}{{\text{l}}^{3 + }} > {{\text{F}}^ - }\)
