Which statement is true about the lagomorph and cavy stomach?

Explanation:
The main idea is that these species have a very strong gastroesophageal barrier. In lagomorphs and cavies, the cardiac (lower esophageal) sphincter is tightly closed, which prevents contents from moving back up into the esophagus and makes vomiting very difficult or virtually impossible. That’s why describing a strong cardiac sphincter as true fits what actually happens in their stomachs. The other statements don’t align with their physiology—for example, they do not readily vomit, their stomach is not near neutral in pH, and gastric emptying isn’t simply “normal” after meals due to their unique digestive adaptations.
