Nonnative organisms introduced into an area by humans are called indigenous species alien species intruding species species

The correct option is ALIEN SPECIES.
An alien specie refers to a specie which is introduced by human into an ecosystem that is outside its natural habitat either intentionally or accidentally. An alien specie may have either a good effect or a bad effect on its new environment.

Ibelieve the answer is relative humidity  because it makes more sense that way. solar flares usually occur in space it doesn't affect the earth, well it could but it wont make a significant damage.  latitude is land it doesnt do anything. prevailing winds, i dont know the correct meaning for this but i doubt that affects the land so it has to be relative humidity.
