Solution

The correct option is A density ; compressibility
Gases have low density and high compressibility.
The gas molecules are far apart as the intermolecular forces are very weak. Hence, gases have huge volume and low density. Also since the intermolecular distance is large, the gas molecules can be easily compressed.
