D

Verified step by step guidance1
Understand the terminology: 'Monogastric' refers to animals that have a single-chambered stomach, as opposed to 'polygastric' (multiple stomach chambers) or 'ruminant' (animals with a specialized stomach for fermentation).
Recognize that pigs are classified as monogastric animals because they have one true stomach, which is responsible for enzymatic digestion of food.
Eliminate incorrect options: 'Polygastric' refers to animals like cows with multiple stomach chambers, and 'ruminant' refers to animals that chew cud and have a specialized stomach for fermentation. Pigs do not fit these categories.
Note that 'hindgut fermenters' refers to animals like horses and rabbits that digest fibrous plant material in their large intestine or cecum. Pigs are not primarily hindgut fermenters.
Conclude that the correct term to describe pigs is 'monogastric,' as they have a single true stomach for digestion.
