A positive correlation means that as one variable increases, the other variable also increases. In option B, as class attendance drops (decrease in one variable), performance on exams decreases (decrease in the other variable), which actually reflects a positive relationship because the direction of change is the same (when considering the inverse relationship: less attendance leads to worse performance). The other options describe inverse or negative correlations, where an increase in one variable leads to a decrease in the other.
