Which bomb design uses fission to create extreme heat to cause hydrogen fusion in plasma (thermonuclear/Hydrogen bomb)?

Which bomb design uses fission to create extreme heat to cause hydrogen fusion in plasma (thermonuclear/Hydrogen bomb)?

• A. Nuclear Fission Bomb
• B. Gun-Type Fission Bomb
• C. Fusion-only Device
• D. Thermonuclear/Hydrogen bomb

Answer: (D)

Hydrogen bombs rely on fission to ignite fusion. The fission part acts as a trigger that creates extreme heat and pressure, which then drives fusion of hydrogen isotopes in a secondary stage. This two-stage setup lets the device release far more energy than a fission-only design. A purely fission bomb produces energy by splitting heavy nuclei and doesn’t involve fusion. A gun-type fission bomb is a method for achieving fission, not fusion. A fusion-only device would try to fuse without a fission trigger, which isn’t how practical weapons are built. So the design that uses fission to drive hydrogen fusion is the thermonuclear/hydrogen bomb.
