The following are some statements about micelles
I) These are formed as aggregated particles when soap is applied at lower concentrations
II) The tail part of it dissolves the grease deposit or dirt.
III) Hydrocarbon chain of soap micelle is hydrophillic end and its anion part is hydrophobic end.
The correct combination is

• Soaps and detergents behave like true solutions at low concentrations but form colloids above Critical micelle concentration(CMC) which is 10^-4 M -10^-3M due to association
• C₁₇H₃₅COO^-Na⁺ is sodium stearate(soap)
• C₁₇H₃₅ part is Hydrophobic(nonpolar) part(tail)
• COO^- part is Hydrophilic(polar) part(head)
• At low concentration; C₁₇H₃₅COO^-Na⁺ ions present on surface with COO^- groups in water and C₁₇H₃₅  chains staying awayand remain at the surface

Micelles are formed due to association above CMC ;   I is false

The Hydrophobic part dissolves the grease deposit ; II is true

Hydrocarbon chain is Hydrophobic , anionic part is hydrophilic;  III is false
