How does a boiling water nuclear fission rector produce electricity

A nuclear reactor produces and controls the release of energy from splitting the atoms of uranium. Uranium-fueled nuclear power is a clean and efficient way of boiling water to make steam which drives turbine generators.

so the first answer i believe

enriched uranium produces a continuous source of energy through a chain reaction that is controlled by control rods. The energy boils water to create steam, which powers a turbine that turns a generator to produce electricity.

Explanation:

The heart of the nuclear power plant is the nuclear reactor.

In the nuclear reactor, energy is generated by splitting the Uranium atoms. It is cleanest and the effective way to produce steam and generate electricity.  

In the core of the reactor, fission reaction occurs where the Isotope,uranium-235 splits into smaller atoms and large amount of energy and heat is generated. This is a chain reaction reaction and can be controlled by a moderator like graphite.

In boiling water reactor, the reactor core is surrounded by water or sometimes water is directly fed into the reactor core where temperature is very high. Here water changes into high temperature steam which is fed into turbine and the turbine is connected to the generator that produces electricity.

Thus electricity is generated in this way in a boiling water reactor.

the correct answer would be d. hope this !
