The order of ease of oxidation of the ions `F^(-), OH^(-), Br^(-), SO_(4)^(2-)` is _______

Options

A. `SO_(4)^(2-) gt F^(-) Br^(-) gt OH^(-)`
B. `SO_(4)^(2-) lt Br^(-) lt OH^(-) lt F^(-)`
C. `SO_(4)^(2-) gt F^(-) gt Br^(-) gt OH^(-)`
D. `OH^(-) lt Br^(-) lt F^(-) lt SO_(4)^(2-)`

Explanation

`SO_(4)^(2-) lt F^(-) lt Br^(-) lt OH^(-)`
In an electronegative series, ease of oxidation increases from top to bottom
