    D. all of the above

    Explanation:

    Nuclear fusion requires very high temperatures, requiring 100 or even 150 million degrees Celsius, temperatures higher than the sun's core temperatures. So statement A is true.

    Fusion reactions occur in both stars and the sun. In stars it occurs at its center, at high temperatures, while in the sun it occurs in the fusion of hydrogen isotopes to form helium isotopes. This implies that statement B is correct.

    In nuclear fission, radioactive waste is the byproduct of this nuclear process, containing radioactive chemical elements for no practical purpose, while fusion does not produce radioactive waste or other unwanted byproducts and is more energy efficient. This indicates that statement C is correct.

    According to these statements, it is concluded that alternative D is the correct one (all of the above).

    Answer: -

    Nuclear fusion D) all of the above

    Explanation: -

    Nuclear fusion occurs in the stars. It requires a very high temperature to occur.

    Nuclear fusion creates far less radioactive waste than fission.

    As such nuclear fusion is preferable to be used.

    The high temperature of nuclear fusion can at present only be realized in the case of nuclear bomb.
