The correct answer is C. Pleistocene.
The Pleistocene epoch is the geological epoch that lasted from about 2.58 million to 11,700 years ago, spanning the world’s most recent period of glaciation. The Pleistocene is part of the Quaternary period, which began approximately 2.58 million years ago and is ongoing. The Pleistocene is the first epoch of the Quaternary period and is followed by the Holocene epoch.
The Pleistocene is characterized by a series of glacial and interglacial periods. During glacial periods, large areas of the Earth’s surface were covered by ice sheets. During interglacial periods, the ice sheets retreated and the Earth’s climate was warmer.
The Pleistocene is also the epoch during which humans evolved. The first humans evolved in Africa about 200,000 years ago. Humans then spread to other parts of the world, and by the end of the Pleistocene, they had populated all of the Earth’s continents.
The Pleistocene is a very important epoch in Earth’s history. It was during this epoch that humans evolved and spread to all parts of the world. The Pleistocene was also a time of great climate change, with the Earth experiencing a series of glacial and interglacial periods.
The other options are incorrect.
A. The Pliocene epoch is the geological epoch that lasted from about 5.333 to 2.58 million years ago, immediately preceding the Pleistocene epoch.
B. The Oligocene epoch is the geological epoch that lasted from about 33.9 to 23.03 million years ago, following the Eocene epoch and preceding the Miocene epoch.
D. The Eocene epoch is the geological epoch that lasted from about 56.0 to 33.9 million years ago, following the Paleocene epoch and preceding the Oligocene epoch.
