`""(92)^(233)U` is assumed to decay by emitting `alpha`- and `beta`-particles, the possible produce of decay is

Options

A. `""_(82)^(207)Pb`
B. `""_(82)^(205)Pb`
C. `""_(82)^(206)Pb`
D. `""_(82)^(208)Pb`

Answer

C

Explanation

`(238)/(4)=59(1)/(2)` and `(206)/(4)=51(1)/(2)`
`implies ""_(92)U^(238)` is the starting element of 4n+2 series
`implies ""_(82)Pb^(206)` is the possible decay product of this series.
