found it somewhere else than brainly you're welcome :)
The radioactive isotope decay until it becomes a different, stable element, The correct option is C.
Half-life is the average lifetime of all the nuclei of a certain unstable atomic species, half-life is the amount of time it takes for a substance's radioactivity to decrease to half of its initial value.
A radionuclide's half-life is the amount of time it takes for half of its radioactive atoms to decay.
A decent rule of thumb is that you will have less radiation than 1% of the original quantity after seven half-lives.
The radioactive isotope decay until it becomes a different, stable element.
