Patricia Dorsey · Answer 1

Option B same Atomic number and Different Atomic weight

Explanation:

Isotope are those inwhich no of protons (Atomic number) is same and mass number (A=n+Z) is different

Examples: Cl-35& Cl-37

And O-16& O-18

And option C corresponds to Isobars with same mass number and different atomic number.
