Which is the BEST argument in favor of developing nuclear fusion reactors compared to conventional fission reactors as an alternate source of electrical energy?

• The materials produced in a nuclear fusion reactor are not hazardous.

• A nuclear fusion reactor does not need a containment vessel for the fusion reactions. 

• A nuclear fusion reactor boils water to produce steam which will be used to generate electricity.  

• A nuclear fusion reactor must be heated to about 100,000,000 °C for the fuel to reach a plasma state.
