• C. Ordovician Period
  The Ordovician Period was a Paleozoic era interval marked by extensive marine biodiversity, the diversification of early vertebrates and invertebrates, and ending with one of Earth's major mass extinction events.
• D. Permian Period
  The Permian Period was the final period of the Paleozoic Era, marked by the diversification of reptiles and the largest mass extinction in Earth's history at its close.
• E. Devonian Period
  The Devonian Period was a division of the Paleozoic Era characterized by the diversification of fish, the first significant colonization of land by plants and early tetrapods, and major reef-building in the oceans.
• F. None of above.
