• C. A - IV, B - III, C - I, D - II
• D. A - IV, B - I, C - II, D - III

Hint:

Canine Theriogenology Drugs:
Prolactin $\rightarrow$ Pseudopregnancy
Cabergoline $\rightarrow$ Estrus induction Prolactin inhibitor
Mifepristone/Alglepristone $\rightarrow$ Pregnancy termination
$\text{PGF}_{2\alpha} \rightarrow$ Open pyometra medical management.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Theriogenological therapeutics and reproductive pharmacological interventions in canine gynecology.

Step 2: Detailed Explanation:
Matching canine theriogenological drugs/conditions in List I with indications in List II:
- A. Increased Prolactin: The primary hormonal driver of IV. Pseudopregnancy (False pregnancy) in intact bitches.
- B. Cabergoline: A dopamine $\text{D}_2$-agonist that lowers prolactin, used for III. Induction of estrus in bitches (shortening interestrus interval) and treating false pregnancy.
- C. Mifepristone (RU-486 Alglepristone): A competitive progesterone receptor blocker used for I. Termination of pregnancy in bitches without side effects (medical abortion misalliance).
- D. Prostaglandin F2$\alpha$ (Dinoprost Cloprostenol): Causes luteolysis and myometrial contraction for the II. Treatment of open-cervix pyometra in bitches.
Matching sequence: A - IV, B - III, C - I, D - II.

Step 3: Final Answer:
Therefore, the correct matching is A - IV, B - III, C - I, D - II, matching option (C).
