*Urgent* Why are light-years used to measure distances in
space?
A. The speed of light is slower in space.
B. The speed of light is faster than time.
C. Distances in space constantly change.
D. Distances between stars are very large.

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.
