Detergents are sodium of potassium salts...

Detergents are sodium of potassium salts of sulphonic acids. Phosphates are added to commercial detergents because they form complex with metal ion that contributes water hardness and keep them dissolved. They also control acidity and micelle formation. Phosphates arediscouraged because there is overgrowth of vegetation and decay of dead plants reduceamount of dissolved oxygen. 
Which of the following are cationic detergents ? 

A

`[CH_3(CH_2)_(15)N(CH_3)_3]Cl`

B

`CH_3(CH_2)_16COO(CH_2CH_2O)_(11)CH_2CH_2OH`

C

`CH_3(CH_2)_(16)OSO_3Na`

D

`C_(17)H_(35)COONa`
