Answer:
The correct answer would be option C.
Mycelium refers to the vegetative part of a fungus which is formed by the mass of branching, thread-like hyphae.
It helps in the absorption of nutrients from the surrounding environment. The biological polymers are first converted or digested into monomers with the help of enzymes secreted by the hyphae.
These monomer units are then absorbed by the mycelium either through facilitated diffusion or active transport.
