B. It can create animals that may be weak. Since a clone is a copy of the original, if the original has some kind of deformity or susceptible to a particular disease, then all clones will be susceptible to that disease as well as well as having some deformities. For example if we cloned plants all with the same genetic identity, and a disease that the plant is susceptible to catching makes one plant sick, all the plants will become sick. There is no genetic variety. And if no favorited traits pass on from parent to offspring, then likely the species will grow weak.
