Final answer:
Breeding facilities should have taller and stronger fences to prevent escapes and protect both animals and humans due to the particular needs of housing breeding animals.
Step-by-step explanation:
The correct answer to which facilities should have taller and stronger fences is d) Breeding facilities. This is to ensure the safety of both the animals and the people. Breeding facilities often contain animals with higher value and with specific temperaments or behaviors that require secure containment. Moreover, these facilities may house aggressive or territorial animals, especially during mating seasons, making it imperative to prevent escapes and unauthorized entry. In contrast, pastures, stalls, and riding arenas typically have different safety and containment requirements and might not need as substantial fencing as a breeding facility.
