Solution

The correct option is A $^{14} C$
The most normally utilized radiometric dating strategy is radiocarbon dating. It is likewise called carbon-14 and C-14 dating. This system is utilized to date the remaining parts of natural materials. Dating tests are normally charcoal, wood, bone, or shell, yet any tissue that was ever alive can be dated.
So, the correct option is '14C'.
