Fifteen-Year-Old Adam Is Obsessed with Violent R-Rated Movies and Lately

Fifteen-year-old Adam is obsessed with violent R-rated movies and lately has started exhibiting violent behaviours himself. His mother believes Adam's behaviour is a result of what he sees in the movies. On the other hand, Adam's father thinks that things are not that simple and Adam's violent behaviour is not just a product of his environment, but also due to personal factors. Apart from his violent outbursts, Adam appears to be bashful and tentative in social situations.
-Imagine two hypothetical scenarios: Scenario 1: Adam has an identical twin reared in a different household by different parents from Adam.

Which of the following cases is most likely

A) The identical twin reared apart would have a personality similar to Adam's.
B) The fraternal twin reared in the same house would have a similar personality to Adam's.
C) An identical twin reared apart and a fraternal twin reared together would have the same chance of having a personality similar to Adam's.
D) We can't make any inferences because the environment has a stronger effect on personality than genetics.
