The correct option is Africa and South America.
Explanation
Alfred Wegener, in his Continental Drift Theory (1912), proposed that all continents were once united in a single supercontinent known as Pangea. One of the primary evidences he presented to support this hypothesis was the morphological matching of coastlines across vast oceans, termed the "Jig-Saw-Fit".
Analysis of the Evidence
- Africa and South America: The most remarkable and apparent "Jig-Saw-Fit" exists between the Atlantic coasts of Africa and South America. The bulge of Brazil (South America) fits almost perfectly into the Gulf of Guinea (Africa).
- Scientific Validation: While the present-day shorelines show a good fit, the match is even more precise when aligned along the continental slope. In 1964, Bullard used a computer program to fit the continents together at the 1,000-fathom line (approx. 2,000 meters depth), demonstrating a near-perfect geometric match with minimal gaps or overlaps.
- Other Matches: While North America and Europe, as well as Australia and Antarctica, also show connections within the Pangea reconstruction, the visual and geometric fit between South America and Africa is the most distinct and historically significant evidence cited for continental drift.
Key Takeaway: The "Jig-Saw-Fit" is a morphological evidence supporting Continental Drift, most clearly demonstrated by the interlocking shapes of the opposing coastlines of South America and Africa across the Atlantic Ocean.
