Correct Answer - a
When uranium is bombarded by slow neutrons the reaction is represented as `._92^235U + ._0^1n to ._56^144Ba + ._36^89Kr + 3_0^1n`+Energy
As more neutrons are produced , the reason is correct.
There are additional neutrons strike uranium nuclei to produce even more neutrons. Thus a chain reaction is established.
