The correct answer among the choices given is option A. For a fusion reaction to happen, matter needs to be in the plasma state. For fusion reaction to happen special conditions should be met to overcome the energy required. One is that the temperature should be high to give atoms enough energy to overcome any resistances. It requires about 100 million Kelvin of temperature. At this point, hydrogen occurs as a plasma.
....Im trying nnot to laugh... whats the question tho?
Organisms (belonging to the same species) may adapt in different ways to better exploit different environments or resources-- survival of the fittest. They also may evolve varied characteristics for attracting mates for reproduction. This means that different groups evolve differently. Over time, these groups or populations may become so different that they can no longer breed together -- and separate species are formed.
