U^238 decays into Th^234 by the emission of an a-particle. There follows a chain of further radioactive decays, either by alpha-decay or by beta-decay. Eventually a stable nuclide is reached and after that, no further radioactive decay is possible. which of the following stable nuclides is the end product of the U^238 radioactive decay chain ?
A. Pb^206
B. Pb^207
C. Pb^208
D. Pb^209

Correct Answer - A
(a) (4n + 2) series starts from U^238 and its stable end product if Pb^206`.
