Not attemptedCorrect Answer: (c) I, II and III
All three lines are accepted geological clues for continental drift: (I) a belt of Precambrian rocks on the Brazilian coast aligns perfectly with rocks in West Africa ([britannica.com](https://www.britannica.com/science/continental-drift-geology?utm_source=openai)); (II) Ghana’s rich placer-gold deposits are traced to source veins in Brazil, implying the two coasts were once joined ([pwonlyias.com](https://pwonlyias.com/upsc-notes/continental-drift-earth-geological-evolution/?utm_source=openai)); (III) the typical Gondwana tillite–sandstone–coal sequence found in India recurs on at least six other southern-hemisphere landmasses, betraying a former super-continent connection ([pwonlyias.com](https://pwonlyias.com/upsc-notes/continental-drift-earth-geological-evolution/?utm_source=openai)). Consequently, statements I, II and III are all correct.
