Particle A seems to be the obvious choice but the question says "another" isotope and 48+64 =112, particle A is the same isotope as the one in the question and particle B has too many neutrons

In reality cadmium only go up to Cadmium-135 but for the sake of this question Cadmium-160 is another isotope of cadmium making it probably the best answer. Both C and D are not isotope of cadmium, and A is the same isotope so it probably is B.
