I think the answer is D, but i'm just guessing...

I think it's A. CO2 and water are products of aerobic respiration only, so species B must be a heterotrophic bacterium. As for species A, it excretes O2, so we think of photosynthesis - a plant. The only thing I find weird is that glucose is listed as an "excrement", which doesn't really make sense since yes, plants produce glucose, but it's to store energy instead of being unwanted waste.
