Which constraint most severely limits practical cold fusion?

💡 Explanation

The Coulomb barrier limits cold fusion because overcoming electrostatic repulsion mandates extremely high reactants kinetic energies; therefore, negligible fusion occurs at low temperatures, rather than rapid fusion which is needed to generate heat and overcome electrode degradation.
