Answer 2

The number of tetrahedral voids and octahedral voids present in a hexagonal primitive unit cell is (d) 12,6

- There are a total of 12 tetrahedral voids present in a hexagonal primitive unit cell.

- The no of octahedral voids present in a hexagonal primitive unit cell is 6.

- Hence, the correct answer is option (d).
