In any closed-packed structure containing N number of particles, the number of Tetrahedral Voids is 2N and the number of Octahedral Voids is N.

Now since in a hexagonal closed packed structure, the number of particles is 6, the number of Tetrahedral and Octahedral Voids will be 12 and 6 respectively.

Therefore, the correct option is (4).
