Which explains why the reflex reaction is important in certain situations?
A. Sending a message up the spinal cord takes time.
B. The brain does not control motor neurons.
C. There are no neurotransmitters in interneurons.
D. Sensory neurons are very slow to form action potentials.

The correct answer is c

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.
