A real gas is expected to exhibit maximum deviations from ideal gas law at:

Alow T and high P
Correct Answer
Blow T and low P
Chigh T and high P
Dhigh T and low P

Solution

At low temperature and high pressure, the molecular motion tends to become low. The intermolecular forces of attraction become significant and the molecules come near each other. So, there is a deviation from ideal behaviour because, in an ideal gas, we assume that the molecular interaction terms become negligible.

Hence, the correct answer is option $$\text{A}$$.
