{'sodium metal': [0, 0, 0, 1], 'kerosene oil': [0, 0, 0, 2], 'hydrochloric acid': [1, 0, 3, 0], 'alcohol': [0, 0, 1, 1], 'water': [65, 15, 80, 129]}

The correct answer is option 2: Kerosene oil. Sodium metal should be stored in kerosene oil because it reacts violently and dangerously with other substances such as water and alcohol.

Option 1: Alcohol is not a suitable storage medium for sodium metal because alcohol can react with sodium and possibly lead to a fire or explosion.

Option 3: Water is a highly reactive substance with sodium metal. When sodium metal comes into contact with water, it reacts vigorously, producing hydrogen gas and heat. This reaction can also result in a fire or explosion.

Option 4: Hydrochloric acid is a strong acid and reacts with sodium metal. This reaction produces hydrogen gas and can be dangerous.

Therefore, kerosene oil is the best option for storing sodium metal because it is an inert substance that does not react with sodium, providing a safe and stable environment for storage. Alert - The correct answer should be option 2: Kerosene oil.
