Which of the following molecules is non-polar in nature?

Noble gases are unreactive because

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

Statement I: Acid strength increases in the order given as $\mathrm{HF}<<\mathrm{HCl}<<\mathrm{HBr}<<\mathrm{HI}$ Statement II: As the size of the elements $F,\mathrm{Cl},\mathrm{Br},I$ increases down the group, the bond strength of $\mathrm{HF},\mathrm{HCl}$ $\mathrm{HBr}$ 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.

The incorrect statement among the following is:
