Respuesta :
Isotopes are two atoms with the same number of protons, but a different number of neutrons. Because they have the same number of proton they are atoms of the same element, but with different masses.
so, the answer is c.

Answer:
C) isotopes of the same element
Explanation:
An isomer is molecule with the same atoms as other but with a different distribution (position, optic, spacial, geometrical, etc).
This applies to molecules and not to atoms. (options A and B can't be)
The isotopes are two atoms of the same element (equal proton number) but with different mass number. This is the case of I-131 and I-133. SO option C is correct.
Also, I-131/Xe-131 and I-133/Cs-133 are two pairs of isobars (two atoms of different elements with the same mass number).
