Answer:

b  is constant

Explanation:

The half-life of a radioisotope is constant throughout its life cycle.

Half-life is the time taken for half of the radioactive nuclei to disintegrate.

Every radionuclide has its characteristic half-life and it is independent of the number of radioactive atoms.

  • The half-life does not depend on any variable. It is an inherent property of a radioactive isotope.
  • The shorter the half-life, the faster a radionuclide decays.
  • Nuclides with a long half life are fairly stable for a long period of time.
  • The decay of a radioactive element is usually characterized by its half-life.

Therefore, the most ideal statement about half-life is that it is constant.
