← ScienceWhich outcome occurs when Carbon-14 concentration declines within fossilized matter?
A)Radiocarbon dating provides age estimation✓
B)Stable carbon isotopes become radioactive
C)Material becomes suitable for combustion
D)Nitrogen-14 concentration proportionally decreases
💡 Explanation
Radiocarbon dating becomes possible when Carbon-14 undergoes radioactive decay obeying first-order kinetics therefore allowing age estimation of the fossil, rather than other isotopic changes, because background radiation would influence other forms of decay.
