The isotopes of the same element in the given options are 21/10 and 22/10 (option A and B).
<h3>What is an isotope?</h3>
Isotopes are two or more forms of an element where the atoms have the same number of protons, but a different number of neutrons within their nuclei.
The above definition shows that atoms of isotopes will have the same atomic number but a different mass number.
Isotopes of the same elements have different number of neutrons and this causes the difference in mass numbers.
According to this question, 21/10 and 22/10 are isotopes of the same element because they have the same atomic number.
