Solution

The correct option is D layer of dispersion medium on their particles
Hydrophillic colloids are water touching colloid particles are attracted towards water.
Their stability is hindered by aggregation and sedimentation phenomenon which are driven by collodial tendency to reduce their surface energy.
Therefore, layer of dispersion medium on their particles will helps to be stable
