The half-life of I-124 is 4.2 days. Which one of the following statements is true?

	a.	After 12.6 days have elapsed, ¼ of the original amount remains
	b.	After 12.6 days have elapsed, 1/8 of the original amount remains.
	c.	It is not possible to know exactly how much remains after 12.6 days because the rate of decay depends on the initial amount.
