Correct Answer

Explanation

Lamarck was right by stating that one could acquire traits through use or disuse of body parts or organs such as development of powerful bulging muscles through constant exercise. However, he was wrong when he thought that these acquired traits could be passed on to offspring and that new species could evolve after several generations by acquiring new traits and losing old ones.
