In the context of Lamarck's ideas on evolution, the trait of a long, powerful trunk in an elephant would be explained as: OD. Gradually, as generations of elephants continued to selectively use and develop their trunks. Lamarck proposed the theory of inheritance of acquired characteristics, suggesting that organisms can pass on traits they have acquired during their lifetime to their offspring. In the case of elephants, if individuals in a population started using their trunks more for tasks like reaching food or defending themselves, over time, this increased use and development of the trunk would be passed on to the next generations. As a result, the trait of having long, powerful trunks would gradually become more prominent in the elephant population through continuous use and refinement across generations.
