List of top Chemistry Questions on Group 18 Elements

Give below are two statements:
Statement-I : Noble gases have very high boiling points. 
Statement-II: Noble gases are monoatomic gases. They are held together by strong dispersion forces. Because of this they are liquefied at very low temperature. Hence, they have very high boiling points. 
In the light of the above statements, choose the correct answer from the options given below.
