B.I and II only
C.I, II and III✓ Correct
D.II and III only
Explanation
All three statements are recognised evidences of continental drift theory proposed by Alfred Wegener. The matching of ancient rock belts between Brazil and West Africa indicates these landmasses were once joined. The gold deposits of Ghana are believed to be derived from the Brazilian plateau, with the source rocks separated by the Atlantic. The Gondwana sediment system found in India has counterparts in Africa, South America, Antarctica, Australia, Madagascar, and the Falklands — six Southern Hemisphere landmasses. All three are standard textbook evidences of continental drift.
