CHXII01:THE SOLID STATE

318746 Assertion :
Total number of octahedral voids present in unit cell of cubic close packing including the one that is present at the body centre, is four.
Reason :
Besides the body centre there is one octahedral void present at the centre of each of six faces of the unit cell and each of which is shared between two adjacent unit cells.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
