Since there is no survival value in an animal' s having an organ that is able to function when all its other organs have broken down to such a degree that the animal dies, it is a result of the efficiency of natural selection that no organ is likely to evolve in such a way that it greatly outlasts the body' s other organs. Of the following, which one illustrates a principle that is most similar to the principle illustrated by the passage? ['One car model produced by an automobile manufacturer has a life expectancy that is so much longer than its other models that its great popularity requires the manufacturer to stop producing some of the other models.', 'A store in a lower-income neighborhood finds that it is unable to sell its higher-priced goods and so stocks them only when ordered by a customer.', 'Automotive engineers find that it is not cost- effective to manufacture a given automobile part of such high quality that it outlasts all other parts of the automobile, as doing so would not raise the overall quality of the automobile.', 'Athletes occasionally overdevelop some parts of their bodies to such a great extent that other parts of their bodies are more prone to injury as a result.']
