Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Ageing is usually defined as the progressive loses of biological function accompanied by decreasing fertility and increasing mortality with advancing age. This process usually occurs after sexual maturation and continues up to the time of maximum longevity (life span) for members. Signs of senility, or extreme old age, are seldom seen in the wild. Animals living under natural conditions rarely approach their maximum possible age because of very high death rates due to infant mortality, diseases, predators, bad weather, accidents, or competition for food and shelter. For this reason, most of the reliable information about the length of the life span comes from the zoos.
Thus, the correct answer is option A.
