Given below are two statements

Statement I : The boiling points of the following hydrides of group 16 elements increases in the order -

H₂O < H₂S < H₂Se < H₂Te

Statement II : The boiling points of these hydrides increase with increase in molar mass.

In the light of the above statements, choose the most appropriate answer from the options given below :

Statement I : Acid strength increases in the order given as HF << HCl << HBr << HI.

Statement II : As the size of the elements, F, Cl, Br, I increases down the group, the bond strength of HF, HCl, HBr and HI decreases and so the acid strength increases.

In the light of the above statements, choose the correct answer from the options given below.

Noble gases are named because of their inertness towards reactivity. Identify an incorrect statement about them.
