Final answer:
The correct order of geologic Eras from oldest to most recent is Precambrian, Paleozoic, Mesozoic, and Cenozoic. The correct option is d. Precambrian, Paleozoic, Mesozoic, Cenozoic
Step-by-step explanation:
The correct order of Eras from oldest to most recent is given by option (d) Precambrian, Paleozoic, Mesozoic, and Cenozoic. The geologic time scale is used to divide Earth's history into eons, eras, periods, epochs, and ages.
The Precambrian is considered a 'super' eon that encompasses the Hadean, Archean, and Proterozoic eons. Following the Precambrian is the Paleozoic Era, which is the era of 'old life' and includes the Cambrian period where there was a great diversity of life that originated.
Next comes the Mesozoic Era, known as the age of reptiles, which includes the Triassic, Jurassic, and Cretaceous periods. The most recent era is the Cenozoic Era, which is the age of mammals, encompassing the Tertiary and Quaternary periods. The correct option is d. Precambrian, Paleozoic, Mesozoic, Cenozoic
