Detailed Solution

All alkalimetals are stored in kerosene.
Reason : Due to their high reactivity with water (or) atmospheric moisture, we can't store them in water.
Na + H₂O→ NaOH + 1/2H₂↑ + Δ
The above reaction is highly exothermic in nature
Therefore, in order to avoid the above reaction, we need to store them in kerosene [inert].
→ But in the case of "Li" ,due to its low density, it floats on the surface of kerosene; that means it gets exposed to atmospheric air, therefore the Li metal is stored in kerosene by wrapping it with paraffin wax material.
→ Density : Na > K
Therefore, statement - I and statement - II are correct.
