Half-life comparison

Substance A Substance B Substance C

Original amount 200 g 400 g 500 g

½ life 6 days 5 days 3 days

From the table of data, substance C will have the least of the original amount remaining after 30 days even though it started with the most.

What is the best explanation for this answer?

A) Substances A and B are not as radioactive since they have longer half-lives.

B) The states of matter for substances A & B are more volatile than substance C.

C) Substances that start with large amounts will always decay at faster rates.

D) Substance C goes through a significantly larger amount of half-lives compared to the other substances.
