Detailed explanation-1: -Starch solution is most stable among the following because it is a lyophilic colloid and the solutions are highly stable due to the high interaction between the dispersed phase and the dispersion medium.

Detailed explanation-2: -Forces of interaction between colloidal particles and liquid are quite strong. Hence, lyophilic sols are very stable and do not precipitate/coagulate easily.

Detailed explanation-3: -The stability of lyophilic sols is a result of two factors, the presence of a charge and the solvation of colloidal particles. On the other hand, the stability of lyophobic sols is only because of the presence of a charge. Thus, the lyophilic sol is more stable than lyophobic sol due to the extensive solvation.
