The correct answer is: a) Pleistocene.
The Pleistocene epoch is the geological epoch that lasted from about 2.588 million years ago to 11,700 years ago, spanning the world’s most recent glacial period. The Pleistocene is part of the Quaternary period, which began approximately 2.588 million years ago at the end of the Pliocene. The Pleistocene is the first epoch of the Quaternary period and covers the period from 2.588 million years ago to 11,700 years ago. The Pleistocene is also known as the Ice Age epoch, as it was a time when glaciers covered much of the Earth’s surface.
The Pleistocene epoch is divided into two periods: the Early Pleistocene and the Late Pleistocene. The Early Pleistocene lasted from about 2.588 million years ago to 781,000 years ago. The Late Pleistocene lasted from about 781,000 years ago to 11,700 years ago.
The Pleistocene epoch is characterized by a number of important events, including the following:
- The formation of the Himalayas and the Alps
- The development of modern humans
- The extinction of many large mammals
The Pleistocene epoch is an important time period in Earth’s history. It was a time of great change and upheaval, and it is the time period that gave rise to modern humans.
The other options are incorrect because they are not geological periods. The Miocene epoch lasted from about 23.03 to 5.333 million years ago, the Jurassic epoch lasted from about 201.3 to 145.5 million years ago, and the Cretaceous epoch lasted from about 145.5 to 66 million years ago.
