Well it's a choice between ammonia, and trichloromethane.....

Explanation:

Ideality assumes negligible interaction between the gaseous particles. For ammonia, a potent force of intermolecular interaction operates, i.e. hydrogen bonding, and many electron trichloromethane, better known as chloroform, #CHCl_3# is a room temperature liquid, the which is far from being even a non-ideal gas, #"boiling point,"# #61.2# #""^@C#, whereas for ammonia #"boiling point,"# #-33.3# #""^@C#

So to my mind, the answer is #D#...

I would be interested in the answer that your teacher gives for this problem. So would you please oblige?
