b. option I.
♦Whenever sodium metal is kept open it vigorously reacts with oxygen and the moisture which is in the air that can catch fire. Sodium also has quick oxidation and that is the reason they are highly reactive. They can easily cause an explosion if come in contact with atmospheric oxygen in the air.
