The correct answer is (4)
Because air can be compressed.
What you mentioned is right where the container is fixed as the containers have definite volume and definite shape.
As for air, it has no definite volume and no definite shape.

if you transfer 50cm3, the containers will have 100cm3, 120cm3 and 150cm3 respectively.
