Answer:
A. They are all equally related to one another.
Explanation:
In scientific terms, the evolutionary history and relationships of organisms is called phylogeny. Phylogeny describes the relationship of one organism to others, such as which organisms it is thought to have evolved from, which species it is most closely related to, and so forth.
Phylogenetic relationships provide information on shared ancestry but not necessarily on how organisms are similar or different. Scientists use a tool called a phylogenetic tree to show the evolutionary pathways and connections among organisms. A phylogenetic tree is a diagram used to reflect evolutionary relationships among organisms or groups of organisms. Scientists consider phylogenetic trees to be a hypothesis of the evolutionary past since one cannot go back to confirm the proposed relationships. In other words, a “tree of life” can be constructed to illustrate when different organisms evolved and to show the relationships among different organisms.

The horse and donkey, though closely related by sharing a common ancestor, are different species. They have different number of chromosomes hence pairing of homologous chromosomes during fusion of gametes becomes complicated. The mule will have an extra chromosome from the horse hence will have abnormalities such as sterility. A Mule is unable to reproduce due to this same phenomenon. Homologous chromosomes are not well paired for meiosis I.
