B Correct answer
Explanation

Hydrogen bombs (thermonuclear weapons) are based on nuclear fusion - combining light atomic nuclei (like isotopes of hydrogen) to form heavier ones, releasing massive energy. Nuclear fission is used in atomic bombs. The bomb requires fission to trigger fusion initially, but the main destructive yield comes from fusion, not fission alone.
