Select the correct statement(s)
(a) \( \alpha \)-particles are simply helium atoms
(b) \( \gamma \)-rays travels with higher speed as compare to \( \alpha \)-particle and have higher ionization power as compare to \( \beta \)-particle
(c) A loss of \( \beta \)-particles results in the production of isobars
(d) \( \beta \)-particles are considered as the best bombarding particles
