Solution

The correct option is A
1 is correct, 2 is correct and 2 is correct explanation of 1

In frenkel defect, only the position of cation changes, it doesn’t miss from the crystal, it just occupies the interstitial site. So Statement 2 is correct.

As the number of particles in the crystal is not changing, there shouldn’t be having any effect on density. So statement 1 is correct and statement 2 is correct explanation of statement 1.
