Solution

The correct option is D Milk + Water
A suspension is a heterogeneous mixture in which the solute particles start to settle down when left undisturbed, and its components can be seen individually by the naked eye.
‘Milk + Water’ is not an example of suspension as its components do not settle at the bottom of the container. It is an example of a colloid.
