Quizplus · Accepted Answer

Isotopes are atoms of the same element with different numbers of neutrons. In this case, option B has a different code in the third segment, which indicates a different number of neutrons and therefore represents an isotope of the same element. The other options have different codes in segments other than the third, indicating different elements altogether. Option D also has a different code in the second segment, further indicating a different element.
