Step 1: Understanding the Concept:
This matching question evaluates unique species-specific anatomical structures found across different domestic animals and birds.
Step 2: Detailed Explanation:
Let us match the anatomical features to the correct species:
- A. Saccus caecus: A large, blind pocket located at the left (cardiac) end of the simple stomach of the horse. This matches with III.
- B. Lyssa: A J-shaped, fibrous and muscular rod-like structure embedded in the ventral midline of the tongue tip of the dog. This matches with IV.
- C. Gizzard (Ventriculus): The highly muscular, thick-walled organ used by the fowl to grind feed with the aid of swallowed grit. This matches with I.
- D. Suburethral diverticulum: A small blind pouch located immediately ventral to the external urethral orifice in the cow. This matches with II.
Therefore, the correct matching sequence is A - III, B - IV, C - I, D - II.
Step 3: Final Answer
The correct option is (A).
