People do not consume food that are high in cellulose content because we do not have the appropriate enzymes that will aid in properly digesting this type of food. That being said, the answer to this item is the first choice, "People cannot digest cellulose".

Cellulose is a carbohydrate which is present in the plant cells. The cellulose is a polymer with glucose as the monomer units. The monomer units of cellulose is attached by the beta linkages. The cellulose provides structural support to the plant cells by forming micro-tubules. The humans cannot eat the diet rich in cellulose because they lack the enzymes that are needed to digest them. Some animals, such as cows and termites have these enzymes but not the humans.

Hence, the answer is 'people cannot digest cellulose'.
