Explanation:

Part A (Advantages of Nuclear Electricity Generation)

• "It is the cheapest source of energy": Nuclear energy is not the cheapest; renewable sources like solar or wind can be cheaper in some cases, and nuclear has high upfront costs. So this is incorrect.
• "It requires very little fuel": Nuclear fuel (like uranium) has high energy density, so a small amount of fuel produces a large amount of energy. This is correct.
• "It does not generate air pollution or greenhouse gases": Nuclear power plants do not emit CO₂ or air pollutants during operation, unlike fossil fuels. This is correct.
• "It is very secure": Nuclear power plants have security measures, and the fuel supply chain is controlled, making it secure in terms of energy supply (not reliant on foreign fuel imports as much as fossil fuels). This is correct.

• "Nuclear electricity generation requires a lot of fuel": As nuclear fuel has high energy density, it requires very little fuel, so this is incorrect.
• "The danger of a nuclear accident": Events like Chernobyl and Fukushima show the risks of nuclear accidents, which can have severe environmental and health impacts. This is correct.
• "Is the most expensive source of energy": While nuclear has high upfront costs, it's not the most expensive (e.g., some renewable technologies or fossil fuels in certain contexts can be more expensive, but it's not the "most" expensive overall). So this is incorrect.
• "The disposal of radioactive waste": Nuclear waste is radioactive and needs long - term, safe disposal, which is a major challenge. This is correct.
• "None to above": Since there are correct options (the danger of a nuclear accident and the disposal of radioactive waste), this is incorrect.

Answer:

• It requires very little fuel.
• It does not generate air pollution or greenhouse gases.
• It is very secure.
