Two pure samples of radioactive nuclides X and Y have the same initial number of atoms. The half-life of X is T½

After a time equal to 4 half-lives of X the ratio $\frac{n u m b e r o f a t o m s o f X}{n u m b e r o f a t o m s o f Y}$ is 1 / 8. What is the half-life of Y?

$0.25 T_{\frac{1}{2}}$

$0.5 T_{\frac{1}{2}}$

$3 T_{\frac{1}{2}}$

$4 T_{\frac{1}{2}}$
