Among the substances listed, **oxygen gas** is more soluble in cold water than in warm water.
**Explanation:**
- **Gases:** The solubility of gases in liquids generally increases with a decrease in temperature. Therefore, oxygen gas is more soluble in cold water than in warm water.
- **Ionic compounds (sodium chloride, potassium chloride):** The solubility of many salts, like sodium chloride and potassium chloride, typically increases with an increase in temperature.
- **Sugar:** The solubility of sugar (sucrose) also tends to increase with temperature.
Thus, the correct answer is **oxygen gas**.
