A gas behaves most like an ideal gas under conditions of:

Ahigh pressure and low temperature
Bhigh temperature and high pressure
Clow pressure and high temperature
Correct Answer
Dlow pressure and low temperature

Solution

From van der Waals equation
$$\left [P+\frac {a}{V^2}\right ][V-b]=nRT$$
At low pressure and high temperature, intermolecular forces become weak and gas behaves like an ideal gas according to the equation.
