Among the gases and , the gases that show only positive deviation from ideal behavior at all pressures in the graph are

When , it is a negative deviation. It shows that the gas is more compressible than expected from ideal behaviour. When , it is a positive deviation. It shows that the gas is less compressible than expected from ideal behaviour. Only b and c gases showing exclusive positive deviation.
