In their research article on video games and social behavior,Gentile et al. (2009) reported a study in which Singaporean children's exposure to prosocial video games was positively correlated with an index of their tendency to display prosocial behavior.The researchers concluded that the results were consistent with the notion that

A) prosocial behavior does not lead to increases in prosocial video game playing
B) experience playing prosocial video games leads to increases in prosocial behavior
C) a correlation exists
D) there is no relation between prosocial behavior and experience playing prosocial video games

The researchers concluded that there was a positive correlation between exposure to prosocial video games and tendency to display prosocial behavior, suggesting that playing prosocial video games leads to increases in prosocial behavior. Therefore, option B, "experience playing prosocial video games leads to increases in prosocial behavior," is the best choice. Option A, "prosocial behavior does not lead to increases in prosocial video game playing," and Option D, "there is no relation between prosocial behavior and experience playing prosocial video games," are both incorrect. Option C, "a correlation exists," is technically correct but not as specific as option B.
