Solution

The correct options are
A hydrophobic
D water-hating
A metal is in the form of dispersed phase and water is the dispersion medium. The colloid is termed as hydrophobic or water hating.
Hydrophobic colloids do not interact with water. So, they are inherently unstable and generally do not form spontaneously. The particles are not hydrated to an appreciable extent.
