Solution

The correct option is D Beta
Alpha emission results in the decrease of the mass number of the parent nucleus by four, and the atomic number by two.
$A Z X α \to A - 4 Z - 2 Y 1 + 42 He$
Beta emission results only in the decrease of the atomic number of the parent nucleus by one.
$A Z X β \to A Z + 1 Y 2 + 0 - 1 e$
