None of the above. Control rods are movable neutron-absorbing rods (made of boron, cadmium, hafnium, etc.) used to regulate the fission chain reaction — inserting them slows or stops the reaction, withdrawing them increases it.
Why the choices are wrong:
- Not unmovable — they are deliberately moved to control the reactor.
- Not inert — they actively absorb neutrons.
- They do not supply neutrons — they remove them.
- They do not drive the generator — they regulate the reactor that produces heat for the turbine/generator.
