To determine which letters represent sister chromatids, we first recall that sister chromatids are the identical copies of a single chromosome that are still attached at the centromere after DNA replication. They appear as two parallel identical halves of the same color when visualized, because they originate from the same chromosome.

Option A: In the left panel labeled A, the two strands shown are not identical copies of the same chromatid; they appear as two different colors that likely represent homologous chromosomes rather than sister chromatids. This means A does not depict sister chromatids.

Option B: In the right panel labeled B, we see two chromosomes with two chromatids each, but the chromatids within a single chromosome are not identical in color in a way that shows them as a single replicated chromosome; instead, B seems to depict the replicated state across homologous chromosomes but does not clearly illustrate the two identical copies of one chromosome held together. This makes B an unclear or incorrect representation of sister chromatids.

Option C: The label C appears under the paired halves that are the two copies of the same chromosome connected at the centromere, i.e., the two identical sister chromatids produced by replication. The chromatid halves are the same color and remain attached at the centromere, which matches the defining feature of sister chromatids.

In summary, sister chromatids are the two identical copies of a chromosome that stay joined at the centromere after replication. Among the depicted options, the configuration shown in C best fits that description, whereas A and B do not clearly show the two identical copies held together as sister chromatids.
