Which of the following will be most influenced by the amount of organic material?

a. soil color

b. soil texture

c. soil structure

d. number of horizons

A. soil color

I answered correctly the Edge nuity test

B, organic ness (i don't know another word for it.) doesn't change color, or structure, and i don't even think that horizons have to do with organic ness. so the only reasonable answer is B.
