← ScienceWhich outcome occurs when radiocarbon dating organic material?
A)Ratio decrease enables age determination✓
B)Stable isotopes ratio becomes invariable
C)Nitrogen-14 transforms into oxygen-15 slowly
D)Carbon-14 absorption rate increases steadily
💡 Explanation
Radioactive Carbon-14 dating relies on beta decay; therefore, the isotopic ratio decreases over time, because this allows estimating sample age, rather than constant or affected by nitrogen transformation assuming consistent initial level.
