There are four radioactive decay series ...

There are four radioactive decay series called thorium `(4n)`, uranium `(4n + 2)` actinium `(4n + 3)` and neptunium `(4n + 1)` series. Neptunium series is artificial while other three series are natural. The end productsd of each radioacitve decay series have stable nuclei. All natural decay series terminate at lead but neptunium or artificial series terminate at bismuth.
The end product formed in the disintegration of `._(88)Ra^(222)` is

A

`._(81)TI^(304)`

B

`._(82)Pb^(206)`

C

`._(86)Rn^(222)`

D

`._(83)Bi^(207)`
