• B. Neoproterozoic Era
  The Neoproterozoic Era was the final era of the Proterozoic Eon, marked by global “Snowball Earth” glaciations and the emergence of early multicellular life leading up to the Cambrian explosion.
• C. Paleoproterozoic Era

• D. Archean Eon
  The Archean Eon is an ancient geological eon of Earth's history, spanning from about 4.0 to 2.5 billion years ago, characterized by the formation of the first stable continental crust and the earliest known life.
• E. Mesoproterozoic Era
  The Mesoproterozoic Era was a middle division of Earth's Proterozoic Eon characterized by the stabilization of continental cratons, widespread sedimentary basin development, and significant evolutionary advances in eukaryotic life.
