Final answer:
The correct answer is option d. participation in college sports.
Step-by-step explanation:
Among the factors that are known to increase the risk of substance abuse among students, mental health problems, substance use during high school, and genetics and family history of addiction have been identified as significant contributors to the likelihood of developing such behaviors.
However, participation in college sports is not typically associated with an increased risk of substance abuse and may in some cases provide a supportive community structure that deters drug and alcohol use. It is important to understand these risk factors to effectively address and prevent substance abuse in educational settings.
