Both Statement I and Statement II are true
Both Statement I and Statement II are false.
Statement I is correct but Statement II is false.
Statement I is incorrect but Statement II is true.

Statement I and Statement II are both correct.
As the size of the halogen increases, the acidic strength of the hydrogen halide increases.
Also, as the difference in the size of the halogen and hydrogen increases, the bond length increases and the bond dissociation energy decreases.
Lower is bond dissociation energy, more is acidic strength.
The correct answer is option 1.
