- Suspension: Common examples of suspension include the mixture of chalk and water, muddy water, the mixture of flour and water, a mixture of dust particles and air, fog, milk of magnesia, etc.
- A colloid is a mixture in which one substance of microscopically dispersed insoluble particles are suspended throughout another substance.
- True solution is a homogeneous mixture of two or more substances. A true solution is a homogeneous mixture with uniform properties throughout.

Explanation:
The stability of a solution refers to the ability of the particles to remain dispersed uniformly throughout the medium without settling or separating. The order of stability of solutions is determined by the size of the particles and their tendency to settle or remain suspended.
Suspension:
A suspension is a heterogeneous mixture in which the solute particles are larger and do not dissolve but remain suspended throughout the bulk of the medium. Due to their larger size, these particles have a greater tendency to settle down over time. The particles in a suspension can be seen with the naked eye and can be separated from the mixture through filtration. Therefore, suspensions are the least stable of the three types of mixtures.
Colloid:
A colloid is a mixture that is actually heterogeneous but appears to be homogeneous because the particles are uniformly spread throughout the solution. The particles in a colloid are larger than those in a true solution but smaller than those in a suspension, ranging from 1 to 1000 nanometers in size. These particles do not settle easily and remain dispersed throughout the medium for a longer period of time. Due to their intermediate particle size, colloids exhibit a phenomenon known as the Tyndall effect, where they scatter light when a beam of light is passed through the solution. Colloids are more stable than suspensions but less stable than true solutions.
True Solution:
A true solution is a homogeneous mixture in which the solute particles are very small, typically less than 1 nanometer in size. These particles are molecular or ionic in nature and are so small that they do not scatter light. True solutions are the most stable of the three types of mixtures as the particles remain uniformly dispersed throughout the medium and do not settle or separate over time.
Order of Stability:
Based on the particle size and tendency to settle or remain suspended, the correct order of stability of solutions is as follows:
1. True Solution - The smallest particle size and highest stability.
2. Colloid - Intermediate particle size and moderate stability.
3. Suspension - Largest particle size and lowest stability.
Therefore, the correct order of stability of solutions is option 'D', with suspension being the least stable.

The answer should be option a since true solution are very much stable, collide are quite unstable and suspension is unstable
