None of the above

Explanation:
Detailed explanation-1: -A colloid is a mixture where very small particles of one substance are evenly distributed throughout another substance. They appear very similar to solutions, but the particles are suspended in the solution rather than fully dissolved.
Detailed explanation-2: -The particles in a colloid do not fully dissolve and are therefore slightly larger than we see in suspensions: typically between one and 1000 nanometers. Although the particles are larger than in suspensions, the dispersed phase of colloids still cannot be filtered and separated.
Detailed explanation-3: -Milk, ice cream and blood are colloids while urea is a true solution.
