We need to write the atomic symbol and identify which are isotopes or not.

From the diagram-

Number of protons $\left(P_A\right)=4$

Number of neutrons $\left(N_A\right)=5$

$$\begin{gathered} P_B=5 \\ {P}_C=6 \\ {P}_D=5 \\ {P}_E=6 \end{gathered}$$

Isotopes- One of two or more atoms that have the same atomic number(the same number of protons) but a different of neutrons.

No other element has the same number of protons as A, therefore, is no isotope of A.

B has the same number of proton as D. B and D are Isotopes.
