Correct Answer:
Option D —
Sodium
Why Sodium Reacts Violently
Sodium is an alkali metal that is extremely reactive. When it comes into contact with even cold water, it reacts aggressively to form sodium hydroxide and hydrogen gas.
This reaction releases a massive amount of heat. The heat is so intense that it immediately ignites the hydrogen gas being produced, causing a bright yellow flame and often a small explosion. Because it reacts so violently with moisture in the air, sodium must be stored under kerosene or mineral oil to keep it safe.
By contrast, the other options—gold, silver, and copper—are highly unreactive metals. They do not react with cold water, hot water, or even steam, which is why they are safely used to make jewelry, coins, and water pipes.
