According to Hardy Schultz rule, correct order of flocculation value for `Fe(OH)_3` sol is :

A

`K_(3)[Fe(CN)_(6)] gt AlCl_(3) gt K_(2)CrO_(4) gt KBr gt KNO_(3)`

B

`K_(3)[Fe(CN)_(6)] lt K_(2)CrO_(4) lt KBr = KNO_(3)=AlCl_(3) `

C

`AlCl_(3) gt K_(3)[Fe(CN)_(6)] gt K_(2)CrO_(4) gt KBr=KNO_(3)`

D

`K_(3)[Fe(CN)_(6)] lt K_(2)CrO_(4) lt AlCl_(3) lt KBr lt KNO_(3)`
