Which of the following is a true ruminant?

Ruminants digest fibrous plant material by fermenting it in a specialized stomach before it’s fully digested, using a foregut fermentation system with a four-chamber stomach. This arrangement—the rumen, reticulum, omasum, and abomasum—lets microbes break down cellulose from grasses and forages, and the animal often regurgitates and chews cud to further crop the feed. Cattle fit this pattern exactly: they possess the four compartments and rely on microbial fermentation to extract nutrients from fibrous feeds. In contrast, pigs are monogastric and do not rely on rumen fermentation, chickens are birds with a different digestive setup, and fish generally do not possess a true rumen for foregut fermentation.
