Answer

Correct option: D.

$a,c$ and $d$

Cationic detergents have germicidal properties and are expensive, therefore, these are of limited use. Synthetic detergents are cleansing agents which have all the properties of soap, but which actually do not contain any soap. These can be used both in soft and hard water as they give foam even in hard water.
