Answer #1

Option D) It possesses metazoan biomarkers

Reason: Biomarkers which are found from the fossils and thay store the molecular information about the species. when this biomakers were analysed with the help of GC–MS, it gave us major information on taxonomy of dickinsonia. These hydrocarbon biomarkers indicated  sterol distribution in the fossil, from which it allowed the scienctists to find some particular sterols having definitive quantities which was one of the best evidence for figuring out Dickinsonia might be an animal.
