The structures of beryllium chloride in solid state and vapour phase, are :

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.
