The correct answer is (c) the storage and management of radioactive waste.

One of the most deadliest disadvantage of radioactive waste is the its management and handling. The radioactive wastes are disposed off very carefully because if they are not handled with care they are likely to cause harm to the nature, which includes plants and animals both. The storage of the radioactive waste is kept safe so that it should not harm the habitat of people and animals.
