Which of the statements correctly describes the main reason why the long-term storage of high-level nuclear waste is considered to be high-risk?

A. High-level nuclear waste generates a lot of heat and poses a threat to life while it remains at high temperatures. The long-term storage facility must deal with the generated heat.
B. High-level nuclear waste is prone to undergo fission and create a nuclear explosion when left on its own for extended periods of time. Therefore, high-level nuclear waste should be kept under watch all the time.
C. High-level nuclear waste is radioactive for hundreds of thousands of years and remains harmful to all life for that duration. Long-term storage facilities must take this fact into consideration.
D. High-level nuclear waste requires specialized equipment to transport. Very few vehicles that can transport nuclear waste exist and improper transportation vehicles will leak radiation to the environment.
