Plutonium is produced

A As basic raw material
B By neutron irradiation of Uz
C By neutron irradiation of thorium
D Artificially

Correct Answer: By neutron irradiation of Uz

Plutonium is made from U-238.
Pu-239 is normally created in nuclear reactors by transmutation of individual atoms of one of the isotopes of uranium present in the fuel rods.
Occasionally, when an atom of U-238 is exposed to neutron radiation, its nucleus will capture a neutron, changing it to U-239.
