Correct Answer is Option C i.e. <span>production of wastes needing long-term storage.
Reason:
Most of the nuclear power plant uses nuclear fission reaction for generation of electricity. In a nuclear fission reaction, a radio-active nuclei (high atomic mass) is bombarded with fast moving projectile. This results in nuclear disintegration. The mass defect between product and reactant results in generation of energy. The daughter element generated during this event, may also be radio-active in nature. These materials have extremely high half-life. Hence, this waste product needs to be stored safely for long-time so as to minimize the risk of nuclear contamination. </span>
Answer:

For diffusion, it could be: particles have inter- particle spaces between them, particles of matter attract each other, which is the strongest in the case of a solid, little less in liquids, and least in gases, and states of matter that are packed tightly together diffuse slowly.
For Brownian motion, it could be: particles have spaces between them, particles are incredibly small, and that particles are always, continuously moving.
Hope this helps!
