Solution

The correct option is C Assertion and Reason are correct and Reason is the correct explanation of Assertion
Schottky defect is a defect which is produced when one cation and anion are missing from their respective positions leaving behind a pair of holes. The crystal as a whole remains neutral because the number of missing positive ions (cations) and negative ions (anions) is the same.
