Step 1: The binding energy per nucleon is calculated using the binding energy and the number of nucleons in the nucleus.
Step 2: The binding energy per nucleon for \( \dfrac{4}{2} He \) is \( 7.06 \, \text{MeV} \), which is the correct answer, based on the given data.
Final Answer:
\[
\boxed{7.06 \, \text{MeV}}
\]
