A clade includes a common ancestor and all of its descendants. In this scenario, species A, B, and C form a clade, and species F is a sister to this clade. Therefore, any group that includes A, B, C, and F would not be a clade because it would not include species D and E, which form their own clade. The only choice that is a clade is C, which includes the clade formed by A, B, and C, as well as species F.
