Verified Solution

Answer & Solution

Correct Answer

(D) \( \mathrm{He} \)

Step-by-step Solution

Detailed explanation

He (helium) has an unusual property of diffusing throughthe materials such as rubber, glass or plastic.
Increasing order of diffusibility of noble gases are \( \mathrm{Xe} < \mathrm{Kr} < \mathrm{Ar} < \mathrm{Ne} < \mathrm{He} \). All noble gases can diffuse through glass,
rubber and plastic material.
