In a breeder reactor

The correct option is: More fissile materials are produced than it is consumed

A breeder reactor is a type of nuclear reactor designed to generate more fissile material than it consumes. It achieves this by using fertile materials (such as Uranium-238 or Thorium-232) that absorb neutrons during the fission process and subsequently undergo radioactive decay to transform into fissile isotopes (such as Plutonium-239 or Uranium-233).
Since the rate of production of new fissile material exceeds the rate of consumption of the fuel sustaining the reaction, the net amount of fissile material increases over time.
