Which characteristic could help you distinguish between types of fungi?
A. The spores made by the fungi
B. The color of the fungi
C.The growing location of the fungi
D. The shape of the fruiting bodies on the fungi

I think the answer is A, is that correct? If not what is the right answer, please provide reasoning.

(Not sure if this is useful but the types of fungi the question is referring to are club fungi, sac fungi, imperfect fungi, and zygote fungi.)
