because He 's molecular weight is small than each other

Answer:
A) He
Explanation:
Hello,
In this case, as the volume is dwindled and the pressure is increased 10 times the initial one, an increase in the non-ideality of the mixture is shown, thus, the least nonideal gas is the helium since it has the weakest intermolecular forces causing its pressure to be the lowest one.
Best regards.
