High concentration of soap in water, soap behaves as
Molecular colloid
associated colloid
macromolecular colloid
lyophilic colloid
There are some substances that at low concentrations behave as normal strong electrolytes, but at higher concentrations exhibit colloidal behavior due to the formation of aggregates. The aggregate molecule thus formed are called micelles.
So, At high concentrations, soap behaves like associated colloids.
So, Option 2 is correct.
