Answer:

B

Explanation:

Radiometric dating uses naturally occurring radioactive elements such as carbon-14 within the rock or fossil to estimate its approximate age. The half-life of the element must also be known. The amount of the radioactive trace element is compared to, in a ratio, with that of the number of the decay product elements. This approximate age can then be relatively compared to those of other rocks or fossils.
