Solution

The correct option is A Uranium-lead method
  • The dating of fossils using uranium and lead is one of the oldest processes of doing so. 
  • This is also the most redefined methods of fossil-dating. 
  • This process can enable dating of fossils that are around 1 million years to over 4.5 billion years old. 
  • This process has a routine precision in the 0.1–1 per cent range and hence, can be considered the most accurate method of fossil-dating.
  • So, the correct answer is 'Uranium-lead method'.
