Which one among the following statements regarding micelles is not correct?

Statement (b) is incorrect: micelles DO NOT precipitate out of solution; instead, they remain suspended as a stable colloidal dispersion precisely BECAUSE of ion-ion repulsion between the negatively charged carboxylate heads on the micelle surface, which keeps them apart. Statement (a) is correct — soaps are Na/K salts of long-chain fatty (carboxylic) acids. Statement (c) is correct — the hydrophobic tails point inward, trapping grease/oil in the micelle core. Statement (d) is correct — soap solution shows Tyndall effect (scatters light) because it is a colloid.
