The stability of
Sc with respect to alpha, β+, and β- decay is to be determined. Do not consider the possibility of decay by electron capture. The following atomic masses are known: 
He: 4.002603 u 
K: 42.960717 u 
Ca: 46.954543 u 
Sc 46.952409 u 
Ti: 46.951764 u

B) subject to alpha decay only.
C) subject to β+ decay only.
D) subject to β- decay only.
E) subject to β+ or β- decay, but not to alpha decay.
