The answer is correct
The key difference between fission and the spontaneous disintegration of uranium into thorium and helium lies in the process that triggers the nuclear reaction. Fission is a process where a large nucleus, like uranium, splits into two lighter nuclei, typically due to the impact of an external neutron. In contrast, spontaneous disintegration, specifically alpha decay (emitting an alpha particle, which is a helium nucleus), is a natural decay process where the nucleus spontaneously emits an alpha particle, resulting in a lighter nucleus (thorium) and a helium nucleus.
The stuff is not even spontaneous sef
It disintegrates only once dear myschool 
the answer is correct because fission means into 2 light nuclei of equal or closely related mass number not helium.
