Answer & Solution
Correct answer: D. Canines
1. The rabbit dental formula shows zero canines in both jaws.
2. Canines are therefore absent in the rabbit.
3. The gap left between the incisors and premolars is the diastema.
4. Incisors and molars are present in the rabbit, so those options are wrong.
