Solution
The option that represents alpha decay is B. 64148Gdโ62144Sm+24He.
Alpha decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle (consisting of 2 protons and 2 neutrons, symbolized by 24He) and transforms into a new element. In this case, Gd (Gadolinium) decays into Sm (Samarium) and an alpha particle.
