Why Frenkel defect does not change the density of AgCl crystal ?

Which point defect does not lowers density of a crystal.

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.

Which point defect lowers the density of crystal ?

What is the effect of presence of Schottky defects on the density of the crystal?

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

The resistivtiy does not change if

Statement : Due to Frenkel defect the density of the crystalline solid remains same. Explanation : In Frenkel defect, no cations or anions leave the lattice.
