Which stoichiometric defect in crystals increases the density of a solid?

Which point detect in crystals of a solid does not change the density of the solid?

The questions given below consist of an assertion and the reason. Use the following key to choose the appropriate answer. (a) Both the Assertion and the Reason are correct and the Reason is the correct explanation of the Assertion. (b) The Assertion and the Reason are correct but the Reason is not the correct explanation of the Assertion.(c) Assertion is is CORRECT but reason is INCORRECT. (d) If assertion is INCORRECT but reason is CORRECT. (e)If both assertion and reason are INCORRECT. Assertion: Frenkel and Schottky defects are stoichiometric defects REason:Both defects change the density of the crystalline solid.
