The correct answer is B. Suspension
Step-by-step explanation:
In chemistry, a suspension occurs as the particles of a substance (solute) are mixed in a liquid or substance that acts as a solvent. In suspension, particles of the solute are large enough to be seen, also these can be separated through filtering and tend to settle. This differs from solutions because in these substances mix homogenously and from colloids because in these, it is difficult to separate both substances. This implies, the case described refers to a suspension as the substances mixed can be easily separated and the particles of one of the substances settle and can be seen.
