Question

what is one significant advantage of nuclear power?
unpredictable fuel supply
limited environmental impact
high cost of fuel
high emissions of co2

Explanation:

Nuclear power plants produce electricity with relatively low greenhouse gas emissions (unlike fossil - fuel plants which emit high CO₂). The fuel supply (e.g., uranium) is more predictable compared to some other energy sources. Also, the cost of nuclear fuel is not generally considered a significant advantage (it can be high in some aspects like waste management, but not in the context of fuel cost being an advantage). So, limited environmental impact is a valid advantage.

Answer:

B. limited environmental impact
