Question Analysis
This question evaluates the student's understanding of the "Like Dissolves Like" rule and the concept of miscibility.

Key Concept Explanation
The "Like Dissolves Like" rule states that polar solvents dissolve polar or ionic solutes, and nonpolar solvents dissolve nonpolar solutes. Miscibility refers to the ability of two liquids to mix completely.

Step-by-step Solution
1. Identify the polarity of each pair:
Ethanol (polar) and water (polar)
Oil (nonpolar) and water (polar)
Sand (solid, non-soluble) and water (polar)
Oil (nonpolar) and sand (solid, non-soluble)
2. Apply the "Like Dissolves Like" rule:
Ethanol and...
