Carbon-14 has a half-life of 5730 y. A sample of wood has been recovered by an archaeologist. The sample is sent to a laboratory, where it is determined that the activity of the sample is 0.144 Bq/g

By comparing this activity with the activity of living organic matter,
0.230 Bq/g, the scientist determines how old the wood sample is, or more precisely, when the tree that the sample came from died. How old is the sample of wood?
A) 3870 y
B) 4250 y
C) 4590 y
D) 2630 y
E) 2940 y
