The correct answer pertains to the fact that zinc oxide, iron oxide, carmine, mica, and ultramarine colors do not require certification due to their established safety and acceptance for use in cosmetic products. These colorants have a long history of safe use and are considered safe for consumer products, which means they are often exempt from the rigorous certification processes that artificial dyes and fluorescents undergo.

Certification is usually mandated for synthetic colorants, especially those that are artificial or fluorescent, due to their potential for causing allergic reactions or other adverse effects. Natural plant-based colors can also require certain standards but can vary significantly by type and source, leading to less consistent regulation compared to mineral pigments that often are not subjected to the same level of scrutiny.

In contrast, mineral pigments, while often requiring less certification compared to synthetic dyes, do not inherently mean they fall into the same non-certification category as the listed substances. Thus, the emphasis on the established safety profile and regulatory history of zinc oxide, iron oxide, carmine, mica, and ultramarine colors is key to understanding why this group is exempt from certification requirements.
