Hint: As we know that a colloid is a mixture in which one substance of microscopically dispersed insoluble or soluble particles is suspended throughout another substance. Sometimes the dispersed substance alone is called the colloid, the term colloidal suspension refers ambiguously to the overall mixture.
Step by step answer:
When the dispersion medium is gas, the dispersed phase can be solid or liquid but not gas. Colloids of gas with dispersed phase as solids or liquids are called Aerosols. Fog is an example of an aerosol particle thus cloud or fog is a colloidal system in which the dispersed phase is liquid and dispersion medium is gas.
Therefore the correct answer to the question cloud or fog is a colloidal system in which the dispersed phase and dispersed medium are liquid and gas.
Therefore the correct option is Option B.
Additional Information:
Colloids are mixtures in which one or more substances are dispersed as relatively large solid particles or liquid droplets throughout a solid, liquid or gaseous medium.
The particles of a colloid remain dispersed and do not settle due to gravity and they are often electrically charged.
Note: The phase that is scattered or present in the form of colloidal particles is called the dispersed phase.
The medium in which the colloidal particles are dispersed is called the dispersion medium. For example in a starch solution, starch represents a dispersed phase while water presence and dispersion medium.
