Answer:
B) Nuclear plants in the United States have stricter safety guidelines.
Step-by-step explanation:
In nuclear power plant we know that we always use the principle of nuclear fission in which high energy neutrons are used to initiate the nuclear fission and the energy is thus released which is used in different parts.
Nuclear fusion is not possible here in this because nuclear fusion is not controlled easily as well as it requires high energy to initiate the reaction
In Cherobyl plant there exist a nuclear fission reactor which was not maintained proper due to which there was a huge accident.
In this accident huge number of people got harmed and its effect was long lasting as this is not controlled easily
So here correct answer will be
B) Nuclear plants in the United States have stricter safety guidelines.
