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.
1. Both Statement I and Statement II are true.
2. Both Statement I and Statement II are false.
3. Statement I is correct but Statement II is false.
