Which of the following is most similar to the functioning of an electron transport chain? a. a person descending a flight of stairs one step at a time. b. a person jumping from the top to the bottom of a flight of stairs in one jump. c. a rock falling from a cliff. d. a person jumping rope.

I believe the answer is “D) a person jumping rope”

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.
