Correct answer: C

  1. We identify the scientific principle behind a hydrogen bomb.

  2. A hydrogen bomb is also called a thermonuclear bomb. It releases energy by combining light nuclei such as isotopes of hydrogen: 2H+3H→4He+energy^2\mathrm{H} + ^3\mathrm{H} \rightarrow ^4\mathrm{He} + \text{energy}2H+3H→4He+energy

  3. This process is called nuclear fusion, in which small nuclei combine to form a heavier nucleus with a large release of energy.

  4. Now evaluate the options:

    • A: Nuclear fission
      Fission is the splitting of a heavy nucleus like uranium. This is the principle of an atomic bomb, not the main principle of a hydrogen bomb.

    • B: Natural radioactivity
      This is spontaneous emission from unstable nuclei and is not the operating principle of a hydrogen bomb.

    • C: Nuclear fusion
      Correct. A hydrogen bomb works primarily on the basis of fusion of hydrogen isotopes.

    • D: Artificial radioactivity
      This refers to induced radioactivity, not the principle of a hydrogen bomb.

  5. Therefore, the correct answer is: C: Nuclear fusion\boxed{\text{C: Nuclear fusion}}C: Nuclear fusion​
