Charlie's investigation of the relationship between length of commute to work and blood pressure revealed a significant causal effect of time spent commuting on elevated blood pressure. Which of the following could represent this finding?
A) t(45) = 4.21, p = .61, d = .19
B) t(45) = 7.53, p = .04, d = .65
C) t(45) = 2.72, p = .10, d = .23
D) t(45) = 3.99, p = .08, d = .31

The correct choice, B, indicates a statistically significant result (p = .04, which is less than the conventional threshold of .05) and a moderate effect size (d = .65), supporting the conclusion of a significant causal effect of commuting time on blood pressure.
