Discussion
The rocks that were formed 300 million years after the earth was formed, is :
Answer: B
These rocks are located in Western Australia.
The oldest known pieces of the Earth's crust are tiny zircon crystals from the Jack Hills of Western Australia, dated to about 4.4 billion years, only a few hundred million years after the Earth formed about 4.5 billion years ago. Very old rock formations of the Pilbara and Yilgarn regions are also found there.
Such rocks are the oldest in the world, not the youngest, so option A reverses the fact. The Himalaya is a young fold mountain range, and Eastern Europe is not where the oldest known rocks occur.
