A heterogeneous mixture in which the solute particles do not dissolve but remain suspended throughout the bulk of the medium is known as-

Correct option is B

The correct answer is (b) Suspension.
· A suspension is a heterogeneous mixture where the solute particles do not dissolve but remain suspended in the medium. These particles are larger than those in solutions or colloids and can often be seen with the naked eye.
· In a suspension, the solute particles may eventually settle down if left undisturbed.
· Examples of suspensions include sand in water, muddy water, and some medicines where you need to shake the bottle before use.
Information Booster:
· Saturated solution: A solution in which no more solute can dissolve at a given temperature.
· Unsaturated solution: A solution that can still dissolve more solute at a given temperature.
· Colloids: A mixture where very fine particles of one substance are dispersed evenly throughout another, but the particles are too small to settle down (e.g., milk, fog).
