Number of tetrahedral voids occupied in a unit cell of diamond is

Assertion: Diamond has a ccp arrangement in which corners, face centres and alternate tetrahedral holes are occupied by C atoms Reason: In diamond, C atoms at corners are sp^(3) hybridised but at the face centres these are sp^(2) hybridised
