Under which conditions does a real gas approximate to an ideal gas?

Explanation

Real gases approximate ideal gas behavior at relatively low density, low pressure, and high temperature.At high temperatures, the gas molecules have enough kinetic energy to overcome intermolecular forces, but at low temperatures, the gas has less kinetic energy and thus the intermolecular forces are more prominent. At low gas densities and low pressures, there is lots of space between molecules, but at high densities, the molecules are crowded and thus the volume of the gas particles is no longer negligible. Lower pressures mean fewer interactions and those interactions can be more easily thought of as elastic collisions.Hence, D is the correct option.
