Answers
a) All the above statements are correct.
Statement (A): Under high pressure, assuming the gas in a particular vessel or container, the particles or molecules of gas come close to each other which increases the intermolecular attraction between them. Hence the gas is compressed.
Statement (B): At low pressure, the particles or molecules of gas are free to move in the space to cover the whole area of the vessel or container. So the intermolecular spaces between the molecules increases, eventually increasing the volume of the gas.
Statement (C): Under high pressure, as already mentioned in Statement (A), the gas is compressed as the intermolecular force of attraction increases between the molecules. Also at high pressure the gas experiences phase change and it gets converted into liquid.
