Answer:
Some biologists urge the collection of the few remaining individuals of some of the most threate most threatened 3) amphibian species in order to preserve them if they become extinct in the wild. If such captive-breeding programs could produce thousands of individuals from just a few of the remaining survivors, the species will still be threatened because of B) artificial selection
Explanation:
Being an artificial type selection it is difficult for the specie to be reintroduced into its original environment and that needs specific laboratory conditions to survive. In many cases, this situation does not help overcome the threat because the habitat loss condition does not change. Additionally there is no great genetic variability that allows adaptation
