Detailed explanation-1: -The answer is letter B. Explanation: Body structures develop because they are used extensively. The Theory of Use and Disuse stated that the organs not in use will disappear while organs in use will develop.
Detailed explanation-2: -Lamarckism, also known as Lamarckian inheritance or neo-Lamarckism, is the notion that an organism can pass on to its offspring physical characteristics that the parent organism acquired through use or disuse during its lifetime.
Detailed explanation-3: -Lamarckism is considered as a wrong concept because the characters acquired by an organism during its lifetime due to use or disuse do not affect the genetic makeup of the organism. They are simply phenotypic changes. Note: Jean-Baptiste Lamarck, simply known as Lamarck was a French naturalist.
