a slight change in a rabbit’s ability to hear its predators better and help it survive is
A
an adaptation.
B
a vestigial structure
C
an acquired trait
D
an isolation
Explanation: 

Detailed explanation-1: -Ultimately, rabbits are resilient and adaptable. The main adaptations that explain the rabbit’s adaptive success are its nutrition (wide adaptation to food and good nutritional use of caecotrophy), immune system (powerful and developed), and other aspects related to genetics and behaviour.

Detailed explanation-2: -The rabbit’s eyes are set high on the head, and is complimented with a weak but very flexible neck which allows the animal to rotate its head. These adaptations let the rabbit have a greater field of vision, which helps in spotting food as well as predators. They also have strong legs that are made for running.

Detailed explanation-3: -Rabbits also have behavioral adaptations to avoid predators. Sometimes they will hide in shallow ditches to make themselves less visible. Other times they will freeze in place to allow their camouflage to hide them. Finally, rabbits are crepuscular, meaning they are active at dawn and dusk.

Detailed explanation-4: -The long ears of rabbits are most likely an adaptation for detecting predators. In addition to their prominent ears, which can measure up to 6 cm (more than 2 inches) long, rabbits have long, powerful hind legs and a short tail.
