Uranium"lead dating, abbreviated U"Pb dating, is one of the oldest and most refined of the radiometric dating schemes. It can be used to date rocks that formed and crystallised from about 1 million years to over 4.5 billion years ago with routine precisions in the 0.1"1 per cent range.
So according to me, D is the right answer.

Radiocarbon dating (sometimes simply known as carbon dating) is a radiometric dating method that uses the naturally occurring radioisotope carbon-14 (14C) to estimate the age of carbonaceous materials up to about 58,000 to 62,000 years.

Uranium - Lead method:
Knowledge of the rate of decay of certain radioactive isotopes helps to determine the age of various rock deposits Geological rocks have Uranium 256 which decays to uranium 238 and lead 206 ultimately.

D is the right answer.
The age of minerals and rocks is estimated by U-Pb method which is also known as helium dating. Remember: C-14 dating method is used to predict the age of fossils or dead animals or a fallen tree.

The method which is used for calculating oldest fossils is Uranium lead method. Not carbon-14 dating because it has a limitation of calculating only up to 58000 years old fossils.

The method most suitable for calculating oldest geological formations are U-Pb and Rb-Sr method not C14 as it is used for dating the recent events because of its small half life.

U-Pb is the absolutely correct answer. It can tell the age of things formed about 1 million to 4.5 billion years ago.

C-14 used for- plants, trees.
Uranium-Lead used for- ancient geological formation (like limestone, sandstone).
