Solution

The correct options are
A
Tetrahedral voids

B
Octahedral voids

Even in ABCABC close packing, although the $3^{r d}$ layer is arranged in a different way, the kind of voids we observe will be exactly the same.

In the figure above, the green ones are tetrahedral voids and the yellow ones are octahedral voids.
