Solution

The correct option is A
Statement 1 is true, Statement 2 is true; Statement 2 is a correct explanation of Statement 1.

Statement 1: In any ionic solid [MX] with schottky defect, the number of positive and negative ions are same.
Statement 2: An equal number of cation and anion vacancies is present.
$\Rightarrow$ Schottky Defect $\to$ Equal number of anion and cations are missing.
No. of ions decreases, volume remains same $\Rightarrow$ Density decreases.
