A. goat, sheep and pig
B. cattle, sheep and goat
C. pig, rabbit and poultry
D. poultry, rabbit and pig

Answer:

The correct answer is C. Pig, rabbit, and poultry possess stomach chambers.

Stomach chambers are found in animals that practice foregut fermentation, a process in which complex plant materials are broken down by microorganisms before reaching the small intestine.

Pigs have a complex digestive system that includes a stomach divided into several chambers, including the stomach's anterior and posterior regions. These chambers allow for efficient fermentation and digestion of fibrous materials.

Rabbits also possess a unique digestive system with a large, sacculated, and compartmentalized cecum. This cecum acts as a fermentation chamber where microorganisms break down cellulose and other complex plant materials.

Poultry, which includes birds like chickens, also possess a crop, proventriculus, and gizzard, which serve as specialized stomach chambers. These chambers aid in the mechanical breakdown of food and allow for microbial fermentation of plant matter.

Therefore, the animals in group C, which are pigs, rabbits, and poultry, possess stomach chambers as part of their digestive systems to aid in the fermentation and digestion of complex plant materials. Therefore, Option C is correct.
