Answer: Domain.
Explanation: I'm glad that you asked this question. When it comes to to biology and the identification of species, domain is the highest rank that you can find in taxonomy. If you look at the taxonomy ranks, this is the order: Domain > Kingdom > Phylum > Class > Order > Family > Genus > Species.
That is why domain includes all of the rest, because in the pyramid, it is the one at the top.
Answer: Option A) sister chromatids
In mitosis, each chromosome is made up of sister chromatids that carry the same alleles.

Thus, mitosis results in two daughter cells that have the same chromosome make-up as the original parent cell.
