C Correct answer
Explanation

Hydrogen bombs (thermonuclear weapons) work on the principle of nuclear fusion, where light nuclei (like isotopes of hydrogen - deuterium and tritium) combine to form heavier nuclei, releasing enormous energy. This is the same process that powers the Sun and stars. A fission bomb is typically used as the trigger to create the extreme temperatures and pressures needed to initiate fusion.
