Isotopes means elements having same atomic number.

So,

B and D are the Isotopes because both have 6 number of proton which is equal to the atomic number.

Isobars means elements having same atomic mass.

So,

A and D are Isobars because both have same number of atomic mass.

Atomic Mass = Number of proton + Number of Neutron.
