Detailed explanation-1: -Glucans. Glucan is the most important structural polysaccharide of the fungal cell wall and represents 50–60% of the dry weight of this structure.

Detailed explanation-2: -Chitin is a fibrous substance consisting of polysaccharides, which is the major constituent in the exoskeleton of arthropods and the cell walls of fungi.

Detailed explanation-3: -Chitin is an essential component of the cell walls and septa of all pathogenic fungi, and occurs in the cyst walls of pathogenic amoebae, the egg-shells and gut lining of parasitic nematodes and the exoskeletons of invertebrate vectors of human disease including mosquitoes, sand flies, ticks and snails.

Detailed explanation-4: -So, the correct option is ‘Cellulose’.

Detailed explanation-5: -Fungal carbohydrates: Chitin Chitin, a linear (1, 4)-linked polymer of GlcNAc (Fig 1B) derived from a variety of biological sources including the cell walls of fungi and insects, is one of the most abundant polymers in nature.
