Answer:
D. Ecological
Explanation:
Monocular vision in animals (primarily herbivores or prey animals) allows them to see with their eyes independently, rather than acting as a pair, like humans.
This feature is <u>evolutionary</u> in character, allowing these animals to adapt to the conditions of their habitat and predators, giving them a broader view, allowing them to detect threats from as many directions as possible.
However, this type of visual adaptation has its <u>limitations</u>, for example, the depth assessment, not always allowing these animals to see with complete clarity the distance in which the threat lies.
