Which period occurred 360 to 286 million years ago?

1.cambrian
2.carboniferous
3.devonian
4.silurian

Option 2

Explanation:

Carboniferous period can be defined as the fifth division of Paleozoic Era in which the reptiles were seen for the first time. The literal meaning of Carboniferous is carbon containing or carbon producing. Also, in this period most of the earth's coal layers were formed under the large coverings of forests, so the approximate age of coal found was 60 million years which shows that Carboniferous period started 360 million years ago and lasted up-to 286 million years approximately.

Therefore the correct answer is "Option 2- Carboniferous".
