-

-
B.
Suspension
-
C.
Colloid
-
D.
Heterogeneous mixture
Correct Answer:
A. Homogeneous mixture
Explanation:
A homogeneous mixture is formed when a solute, like salt, completely dissolves in a solvent, like water, resulting in a uniform composition throughout. Because the salt particles are distributed evenly at a molecular level and do not settle over time, they become invisible to the naked eye, distinguishing this type of mixture from suspensions or colloids.
