The number of tetrahedral and octahedral voids in a cubic close-packed (CCP) unit cell can be determined based on its structure. In a CCP unit cell, also known as face-centered cubic (FCC), the arrangement of atoms creates specific types of voids.

Void Count in CCP Unit Cell

  • Tetrahedral Voids: There are 8 tetrahedral voids in a CCP unit cell.
  • Octahedral Voids: There are 4 octahedral voids in a CCP unit cell.

Therefore, the correct answer is A. 8, 4.
