Reduction potentials of some ions are given below. Arrange them in decreasing order of oxidising power.
Ion `" " CiO_(4)^(-) " " IO_(4)^(-) " " BrO_(4)^(-)`
Reduction `" " E^(Theta)=1.19 V " " E^(Theta)=1.65 V " " E^(Theta)=1.74`
potential `E^(Theta)//V`

A

`ClO_(4)^(-) gt IO_(4)^(-) gt BrO_(4)^(-)`

B

`IO_(4)^(-) gt BrO_(4)^(-) gt ClO_(4)^(-) `

C

`BrO_(4)^(-) gt IO_(4)^(-) gt ClO_(4)^(-)`

D

`BrO_(4)^(-) gt ClO_(4)^(-) gt IO_(4)^(-)`
