● a. multiple stomachs
● b. inability to vomit
● c. absence of a cecum
● d. absence of a large intestine

Explanation:

Horses (equine) have a digestive system that is different from many other animals. Let's analyze each option:

• Option A: Ruminants (like cows) have multiple stomachs, not horses.
• Option B: Horses have a very strong sphincter muscle at the junction of the esophagus and stomach, making it extremely difficult for them to vomit. This is a unique feature of the equine digestive system.
• Option C: Horses have a large cecum which is an important part of their hind - gut fermentation.
• Option D: Horses have a large intestine which is also crucial for digestion and water absorption.

Answer:

B. Inability to vomit
