Which of the following is a colloid

Colloids, also known as colloidal solutions or colloidal systems, are mixtures in which microscopically dispersed insoluble particles of one substance are suspended in another substance. The size of the suspended particles in a colloid can range from 1 to nanometres 10 -9 metres. For a mixture to be classified as a colloid, its suspended particles must not settle in the manner that the particles of suspensions settle at the bottom of the container if left undisturbed. Colloidal solutions are known to exhibit the Tyndall Effect , which is a phenomenon in which beams of light incident on colloids are scattered due to the interactions between the light and the colloidal particles. Colloids usually feature substances that are evenly dispersed in another. In such mixtures, the substance that is dispersed is referred to as the dispersed phase, whereas the substance through which it is dispersed is called the continuous phase. In simple terms, we can define colloids as a mixture where one of the substances is split into very minute particles which are dispersed throughout a second substance. The minute particles are known as colloidal particles.
