Question Analysis
This question tests the student's understanding of the "like dissolves like" principle, which states that polar solvents dissolve polar or ionic solutes, and nonpolar solvents dissolve nonpolar solutes.

Key Concept Explanation
The "like dissolves like" principle is based on intermolecular forces. Polar solvents (with uneven charge distribution) interact favorably with polar or ionic solutes, allowing dissolution. Nonpolar solvents (with even charge distribution) only dissolve nonpolar solutes, as they cannot form strong interactions with polar/ionic particles.

Step-by-step Solution
1. Identify the polarity of each substance in the given pairs.
2. Apply the "like dissolves like" principle to determine which pair will form a solution:
Option A: Ethanol (polar) and hexane (nonpolar) (will not form a...
