Ideal gas has several important properties that must be followed by real gases to behave like an ideal gas
so here we can say
1. all gas molecules moves at very fast speed in random direction
2. there should not be any interaction force between molecules of gas
3. all gas molecules must have to follow Newton's II law
4. There is no effect of gravity on the molecules of gas
so here if all above conditions are followed by gas then
the condition must be followed only at low pressure and high temperature
so correct answer is
(2) low pressure and high temperature
