Assertion : The formal oxidation no. of sulphur in Na ₂ ~S ₄ O ₆ is 2.5 . Reason : Two S-atoms are not directly linked with O -atoms.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer
