Question Analysis
This question involves applying the "like dissolves like" principle. The main focus is on predicting solubility based on the polarity of the solute and polar water solvent.

Key Concept Explanation
Water is a polar solvent. Polar solutes (e.g., sugar, ethanol) and ionic solutes (e.g., NaCl) can form favorable interactions with water molecules, leading to dissolution. Nonpolar solutes (e.g., vegetable oil) cannot form these interactions, so they do not dissolve in polar water.

Step-by-Step Solution
1. Identify water’s polarity: polar solvent.
2. Apply the "like dissolves like" rule: polar/ionic solutes dissolve; nonpolar solutes do not.
3. Analyze each option:
A: Sugar is polar → dissolves in water...
