Hindgut fermenters are sub-divided based on the primary site of microbial fermentation:
Colon fermenters: Equids (Horse, Zebra), Rhinoceros, and Elephant possess an enormously enlarged, sacculated colon that serves as the predominant microbial fermentation vat.
Cecal fermenters: Lagomorphs (Rabbit), rodents (Guinea pig), and many marsupials utilize an enlarged cecum as their primary fermentation chamber.

Zoological classification of animals:
Artiodactyl (even-toed ungulate) -> Hippopotamus (order Artiodactyla) (III)
Perissodactyl (odd-toed ungulate) -> Rhinoceros (order Perissodactyla) (IV)
Poikilotherm (cold-blooded ectotherm) -> Crocodile (reptile) (I)
Metatherian (pouched marsupial mammal) -> Kangaroo (subclass Metatheria) (II).

Matching the respective taxonomic families in the exact prompt sequence of animals:

• Bear -> Family Ursidae (C)
• Deer -> Family Cervidae (B)
• Wolf -> Family Canidae (D)
• Antelope -> Family Bovidae (A).

Both statements are true: Carfentanil (Wildnil) is an ultra-potent synthetic mu-opioid receptor agonist (approximately 10,000 times more potent than morphine and 100 times more potent than fentanyl) used exclusively in darts for darting, tranquilizing, and chemical immobilization of massive free-ranging wildlife herbivores like elephants, rhinos, and moose (Statement I). Its profound CNS and respiratory depressive actions are rapidly and completely reversed using pure competitive opioid antagonists, specifically Naltrexone hydrochloride at roughly a 100:1 ratio (Statement II).
