The correct option is Western Africa.
Explanation
The question addresses the geological evidences supporting the Continental Drift Theory. One of the primary arguments for this theory is the correlation of ancient rock formations across continents that are currently separated by vast oceans, indicating they were once contiguous.
Detailed Analysis:
- Geological Correlation: A belt of ancient rocks, radiometrically dated to approximately 2,000 million years, located along the coast of Brazil matches perfectly with similar rock formations found in Western Africa.
- Significance: This structural and chronological continuity suggests that South America and Africa were once united as part of the supercontinent Gondwanaland. The rock belts align continuously when the two continents are fitted together.
- Supporting Evidence: The earliest marine deposits along the coastlines of South America and Africa date to the Jurassic period. This indicates that the South Atlantic Ocean did not exist prior to this era, further confirming the separation of these landmasses.
Key Takeaway: The matching of 2,000-million-year-old rock belts between Brazil and Western Africa serves as critical geological evidence for the "Jig-Saw Fit" of continents under the Continental Drift Theory.
