$_{ 92 }^{ 238 }{ U }$ decays into a final product $ _{ 84 }^{ 218 }{ Po }$ by a successive series of emission of alpha and beta particles.

How many alpha and beta particles would have to be emitted to produce $_{ 84 }^{ 218 }{ Po }$ ?

$$_{ 92 }^{ 238 }{ U }\quad \rightarrow \quad _{ 84 }^{ 218 }{ Po }$$

A

$3\alpha +2\beta$

B

$4\alpha +2\beta$

C

$5\alpha +2\beta$

D

$6\alpha +3\beta$
