Select the correct answer.
In which location would a free neutron from a decaying U-235 atom be most likely to cause another atom to split?
OA
in a sample of naturally occurring uranium
B.
in a sample of enriched uranium
O C.
in a sample of rock or soil
D.
in the Sun's core
E.
in a distant star

Decaying of U-235 atom is a process of nuclear fission. In this process a neutron is bombarded on U-235 and the uranium atom captures the neutron and divide immediately to release neutron. With the release of one neutron another nuclear fission process starts.

The free neutron is then split in a sample of enriched uranium because splitting nucleus releases high energy and enrich uranium increases the percentage of uranium-235 which further undergoes fission. This is why enrich uranium samples are used in atomic reactors.

Hence, the correct option is B.
