Correct answer: D. All A., B. & C.
- A. Evaporation & chemical precipitation
- B. Biological methods & adsorption in ion exchange materials
- C. Fixing into a solid mass with cement and sinking deep in the sea
- D. All A., B. & C.
Explanation
Radioactive wastes may be concentrated by evaporation, treated by precipitation or ion exchange, and immobilised in cement before controlled disposal. Therefore, all three listed groups represent recognised treatment or disposal approaches.
