Assertion : Due to Frenkel defect, there is no effect on the density of the crystalline solid. Reason : In Frenkel defect, no cation or anion leaves the crystal.

  • Correct answer
    A
    If both assertion and reason are true and reason is the correct explanation of assertion.
  • B
    If both assertion and reason are true but reason is not the correct explanation of assertion.
  • C
    If assertion is true but reason is false.
  • D
