  2. Both assertion and Reason are true but Reason is not the correct explanation of Assertion.
  3. Assertion is true but Reason is false.
  4. Both Assertion and Reason are false.
Assertion: Increasing order of acidity of hydrogen halides is HF < HCl < HBr < HI
Reason: While comparing acids formed by the elements belonging to the same group of periodic table, H-A bond strength is a more important factor in determining acidity of an acid than the polar nature of the bond.
