(B) No,they do not have the same binding energy.
Binding energy depends on the number of protons and neutrons in the nucleus.
For $_{1}H^{3}$ (Tritium),the nucleus consists of $1$ proton and $2$ neutrons.
For $_{2}He^{3}$,the nucleus consists of $2$ protons and $1$ neutron.
The binding energy per nucleon is influenced by the nuclear force,which is attractive between nucleons.
Since $_{1}H^{3}$ has a higher neutron-to-proton ratio and different pairing effects,its total binding energy differs from that of $_{2}He^{3}$.
In general,$_{1}H^{3}$ has a binding energy of approximately $8.48 \text{ MeV}$,while $_{2}He^{3}$ has a binding energy of approximately $7.72 \text{ MeV}$.
Therefore,the binding energies are not the same.
