A sample contains \( 16 \mathrm{~g} \) of a radioactive material, the half life of which is two days. After 32 days, the amount of radioactive material left in the sample is
[NCERT 1984; MNR 1995; MP PMT 1995]
(a) Less than \( 1 \mathrm{mg} \)
(b) \( \frac{1}{4} \mathrm{~g} \)
(c) \( \frac{1}{2} g \)
(d) \( 1 g \)
