What is a hydrogen bomb?

a) Material formed from decaying leaves and other organic matter
b) A nuclear weapon that releases atomic energy by union of light (hydrogen) nuclei at high temperatures to form helium
c) Unit for measuring the power of motors and engines
d) A severe tropical cyclone usually with heavy rains and winds moving a 73-136 knots

The correct answer is: b) A nuclear weapon that releases atomic energy by union of light (hydrogen) nuclei at high temperatures to form helium

A hydrogen bomb is a type of nuclear weapon that uses fusion reactions to create an enormous explosion. It is different from an atomic bomb, which uses fission reactions to split large atoms and release energy. While option A might seem like a possible answer, it is actually describing compost, not a hydrogen bomb. Option C is referring to horsepower, which is a unit used to measure the power of engines, not the destructive power of a weapon. Option D is describing a hurricane, which is a natural weather phenomenon caused by the rotation of the Earth and temperature differences in the atmosphere, rather than a human-made weapon.
