Answer:
Option D.
Example of a species is a donkey and a horse mate to produce a mule that is sterile and is unable to produce babies.
Step-by-step explanation:
- Species is the group of organisms that interbreed or have the potential of interbreeding in nature.
- Even if they look very different in appearance but interbreed then simply they are species.
- The organism that reproduce asexually cannot be mentioned under species.
- Some animals form naturally hybrid and mostly mate with their own groups.
- So donkey and horse mates to produce a new living, which is considered as the species.
