Question Analysis
This question involves distinguishing solutions from other types of mixtures. The main focus is on recognizing the homogeneous nature of solutions and contrasting it with heterogeneous mixtures like colloids.

Key Concept Explanation
Solutions are homogeneous mixtures with uniform composition and no visible particles.
Fog is a colloid—a heterogeneous mixture where tiny water droplets are suspended in air but do not dissolve.
The droplets are large enough to scatter light (which is why fog is visible) and do not form a uniform mixture at the molecular level.

Step-by-Step Solution
1. Recall that solutions are homogeneous; non-solutions are heterogeneous.
2. Analyze each option:
A: Lemonade is a homogeneous liquid solution → eliminate.
B: Fo...
