At a certain 'start' time for a decay experiment, a radioactive sample is decaying at a rate of $24{,}000 \text{ decays per minute}$. At a time $6\text{ hours}$ beyond the start time, the sample is undergoing $6{,}000 \text{ decays per minute}$.

Which of the following values is closest to the sample's decay rate at a time $9\text{ hours}$ beyond the start time?

A

$0\text{ decays per minute}$

B

$750\text{ decays per minute}$

C

$1{,}500 \text{ decays per minute}$

D

$3{,}000\text{ decays per minute}$
