The correct answer is: C. Upper and Lower Gondwana
The Gondwana Supergroup is a group of sedimentary and igneous rocks that were deposited during the Neoproterozoic and Early Paleozoic eras. It is the most widespread rock group in the geological formation of Chhattisgarh. The Gondwana Supergroup is divided into two major groups: the Upper Gondwana and the Lower Gondwana.
The Upper Gondwana is composed of sandstones, shales, and limestones that were deposited in a marine environment. The Lower Gondwana is composed of sandstones, shales, and conglomerates that were deposited in a continental environment.
The Gondwana Supergroup is important because it contains evidence of the evolution of life during the Neoproterozoic and Early Paleozoic eras. It also contains evidence of the breakup of the supercontinent Gondwana.
The other options are incorrect because they are not the most widespread rock groups in the geological formation of Chhattisgarh.
- Archean and Cudappa are rock groups that are found in the Indian state of Andhra Pradesh.
- Dharwar and Deccan are rock groups that are found in the Indian state of Karnataka.
- Granite and Laterit are rock types that are found in many parts of the world.
