Which outcome occurs when a Carbon-14 sample reaches equilibrium?

💡 Explanation

Equilibrium is reached when the decay rate of C-14 equals its production rate within the environment through **radioactive equilibrium**, because isotopes are continuously created and destroyed leading to a constant ratio; therefore, A is correct rather than completely stopping or reaching a critical mass.
