The correct option is a) absence of enzyme cellulase
Explanation:
- Cellulose is an important polysaccharide compound that is present in the plants.
- Infact, cellulose is the main component from which plant cells walls are made.
- Animals, which feed on plant material usually can break cellulose because they contain the enzyme cellulase for breaking down of cellulose.
- As for humans, they cannot produce cellulase and hence, humans can't digest cellulose.
