Exam Evolution and the diversity of life

Allen and rose are discussing saprotrophs. Allen says saprotrophic fungi decompose the remains of animals and plants. Rose says saprotrophic fungi remove excess lignin from paper to pulp, who is correct?

(B) Both Allen and Rose are correct. Saprotrophic fungi gain their nutrition from organic material that is also non living. This is why Allen is correct in saying that they decompose the animal remains and plants. While typical wood decaying saprotrophs are not capable of breaking down the lignin, basidiomycete, known as wood rot fungus does break down and consume the lignin.
