Answer: D. Adults who have suffered childhood traumas commit more crimes than adults who have not suffered.
Explanation:
A positive relationship between variables means that the variables move together in the same direction as a result of interaction between one another. What this means is that when one of them increases, the other one increases as well and when one reduces, the other one reduces.
The above is a positive relationship because the more childhood traumas that an adult went through, the more they will be prone to committing more crimes as adults. The variables are therefore both increasing at the same time thereby making them positively correlated.
