It oxidizes quickly when exposed to air and reacts violently with water, producing enough heat to burn the hydrogen created in the process.
Because in air potassium is easy oxidized.
as it reacts with the oxygen in the air
Group 1 metals are stored under oil because they are so reactive, they will react with the oxygen in the air if you leave them unprotected, but will also react with water, therefore they need to be stored in oil.
Because they are highly reactive as they react with air, oxygen and moisture readily even at room temperature.
because they react to oxygen
No. Potassium will react violently on contact with water. Potassium is stored under oil to protect it from air and water.
The pure metal must be stored under oil to protect it from oxygen and water vapor in the air.
Because in air potassium is easy oxidized.

Potassium is a metal at normal temperatures. It has to be stored under oil otherwise it will react with oxygen in the atmosphere, possibly dangerously.
sodium lithium Alkali metals are often stored under oil.
as it reacts with the oxygen in the air
Potassium is chemically very active. It will react with oxygen and/or water vapor in the air, so it is stored under oil to keep it out of contact with the air. It doesn't react with the oil.
Group 1 metals are stored under oil because they are so reactive, they will react with the oxygen in the air if you leave them unprotected, but will also react with water, therefore they need to be stored in oil.
I dont think there is a metal stored under water because they react with water and instead are stored in kerosene or oil. Water often corrodes the metal producing rust so i cant think of any metal that would be stored under water.
it can b stored in oil
Any of the alkali metals: lithium, sodium, potassium, etc.
