How would you describe the sequence of reactions in a hydrogen bomb

A hydrogen bomb is a  nuclear bomb, like an atomic bomb, where the explosive energy comes from as nuclear reaction.  

A hydrogen bomb is about fusion — fusing atomic nuclei together to combine into bigger ones.

A hydrogen bomb, or a thermonuclear bomb, contains a fission weapon within it but there is a two-stage reaction process.

The U.S. used two atomic bombs in World War II against Japan, Then, in 1952 and 1954

In particular, monitors will be looking for isotopes of a gas called xenon, which is typically present in H-bomb reactions.

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
