← ScienceWhich outcome occurs during carbon-14 dating of fossils?
A)Ratio change causes age determination✓
B)Isotopes become stable through transmutation
C)Radioactive absorption impacts solar radiation
D)Electron capture prevents further decay
💡 Explanation
Radiocarbon dating relies on measuring the remaining carbon-14, because the known decay rate via beta decay (where neutron transforms into proton) gives its age. Therefore, ratio change indicates age, rather than other isotopes transmutating or absorption of radiation.
