Which outcome increases when the average binding energy per nucleon diminishes in isotopes heavier than iron?

A)Alpha decay half-life decreases
B)Neutron induced fission probability rises
C)Spontaneous fission occurrence declines
D)Nuclear fusion reaction efficiency stabilizes

💡 Explanation

When binding energy per nucleon is reduce, the nucleus becomes less stable; therefore the likelihood of neutron induced fission increases because there's less energy required to cause the nucleus to split, rather than decaying via alpha emission or being stable due to lower fissionability
