Which is a true statement about ideal gas in a container?

a) At constant temperature and a fixed amount of gas, when the pressure changes from P to 2P, the volume doubles.

b) At constant pressure and a fixed amount of gas, when the temperature increases from 20°C to 40°C, the volume doubles.

c) At constant pressure and constant volume, when the temperature changes from 100°C to 200°C, the number of gas molecules decreases by 50%.

d) At constant pressure and a fixed amount of gas, the volume is 0 L at 0 K.

e) All of the above are false statements.
