Answer: D. Gradually, as generations of elephants continued to selectively use and develop their trunks.

Explanation: Lamarck believed that organisms pass on traits to their offspring that they had acquired through use or diuse during their lifetime. In this example, the theory would be that over time, elephants used their trunks in such a way that they became long and powerful.
