The basic physical characteristics of any radioactive material is it's radioactivity itself.

But the radioactive materials decay over the passing time period.

Due to the unstable molecular nature of the radioactive materials,we calculate the half time of for this decaying process.

After the halftime the other remaining radioactive material's decaying time is unpredictable.

That's why the disintegration time of the radioactive materials after their first half time,is taken as the infinite.

That's why the correct answer of this question is option D.
