A. Separated twins develop traits that differ according to the environments in which they are raised.

Explanation:

Despite sharing exactly the same DNA, identical twins can have completely different personalities. Until now, researchers did not know exactly by what mechanisms individuals overcame their genetic programming and differentiated themselves throughout life, forming their individuality. However, after some research, the scientists concluded that the environment has some influence on the personality of the twins. They believe that identical twins who were created separately have different personalities due to the influence of the environments.
