The least plausible assumption is that the quarks internal to the selected nucleon are non-relativistic, as quarks are fundamentally relativistic due to their high speeds and the effects of quantum chromodynamics. The other assumptions regarding interactions and binding forces are more plausible in the context of nucleon interactions."}
