If it is assumed that `._(92)^(235)U` decays only by emitting `alpha and beta-`particles, the possible product of the decay isA. `._(89)^(235)Ac`B. `._(89)^(227)Ac`C. `._(89)^(230)Ac`D. `._(89)^(231)Ac`

Answer» Correct Answer - B
`n_(alpha) = (DeltaA)/(4)` (`DeltaA` change in mass no)
`DeltaA` is divisible by 4 in options (b) and (d)
In option (d), `n_(alpha) =1`
`:. n_(beta) = Delta Z - 2n_(alpha) = 3 - 2 =1`, which is not possible
