| Assertion: In ZnO, the excess \[Z{{n}^{2+}}\]ions are present in interstitial sites. |
| Reason: Metal excess crystals have either missing cation or anion in interstitial site. |
A) Assertion and reason both are correct statements and reason is correct explanation for assertion.
B) Assertion and reason both are correct statements but reason is not correct explanation for assertion.
C) Assertion is correct statement but reason is wrong statement.
