Phrase: Carboniferous system | Statement: [Carboniferous period, stratigraphicSystem, Carboniferous system]

Target entity: Carboniferous system
Context triple: [Carboniferous period, stratigraphicSystem, Carboniferous system]

• A. Carboniferous period chosen
  The Carboniferous period was a Paleozoic era interval, roughly 359 to 299 million years ago, characterized by extensive swampy forests that formed vast coal deposits and by the diversification of early amphibians and insects.
• B. 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.
• C. Silurian
  The Silurian is a geologic period of the Paleozoic Era, roughly 443 to 419 million years ago, marked by the stabilization of Earth’s climate, widespread shallow seas, and significant diversification of early marine life and the first land plants.
• D. 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.
• E. Siderian Period
  The Siderian Period is the earliest division of the Paleoproterozoic, marked by widespread banded iron formation deposition and the initial rise of atmospheric oxygen on Earth.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
