Best answer

Correct Answer - Option 2 : Sodium

The correct answer is Sodium.

Sodium is a highly reactive metal and reacts vigorously with the oxygen, carbon dioxide, and moisture present in the air such that it may even cause a fire.
To prevent this explosive reaction, Sodium is kept immersed in kerosene because Sodium doesn't react with kerosene.

If it is kept in the open air, it easily reacts with the oxygen and catches fire. Since kerosene is a mixture of hydrocarbons, it won’t react with it.
It is a soft metal, reactive, and with a low melting point, with a relative density of 0.97 at 20ºC (68ºF).
From the commercial point of view, sodium is the most important of all alkaline metals.
It reacts quickly with water, and also with snow and ice, to produce sodium hydroxide and hydrogen.
