what general trend occurred over the geologic time periods, from the Precambrian era through the Cenozoic era? A more and more species became extinct B cell developed a nucleous C life became more diverse D more fossils were unearthed and dated

OpenStudy (mathmale):

i don't know much about those geological time periods. however, from experience I can tell you that answer options B and D are quite unlikely to be correct. Have you a textbook or online materials that discuss the Precambrian and Cenozoic eras?
