To calculate the binding energy per nucleon, we first need to calculate the total binding energy using the formula: 
Binding energy (in MeV) = [Z*(proton mass) + (A-Z)*(neutron mass) - atomic mass]*c^2 
= [26*1.0078 + 30*1.0087 - 55.9349]*931.5 = 492.66 MeV

The number of nucleons (protons and neutrons) in the nucleus is A = 56. Therefore, the binding energy per nucleon is: 
Binding energy per nucleon (in MeV) = Binding energy/A = 492.66/56 = 8.79 MeV

Therefore, the best choice is B, with an explanation as shown above.
