d) none of the above

As the temperature of a sample of a radioactive element decreases, the half-life will remain the same

Explanation:

Half-life is defined as the time needed for half of the opening material to modify or decay. Half-lives can be estimated from measures on the variation in the mass of a nuclide and the period it gets to occur. In the period of that substance's half-life, half of the primary nuclei will decompose.

Although chemical changes were raced up or delayed down by varying factors such as temperature, concentration, etc, these factors do not affect half-life. Each radioactive isotope will have its unique half-life that is independent of any of these factors.
