Which outcome occurs when nuclide binding energy asymmetry increases?

A)Spontaneous fission probability greatly increases
B)Beta decay half-life increases rapidly
C)Neutron capture cross-section declines sharply
D)Alpha particle emission becomes improbable

💡 Explanation

Increased asymmetry in nuclide binding energy weakens the nucleus, because the strong force holding it together may be overcome, therefore radioactive decay by spontaneous fission probability increases rather than beta/alpha decay or lowering neutron capture cross-section.
