An HR manager in a factory conducted an analysis of the relationship between duration of production line staff lunch breaks (measured in minutes daily) and staff productivity (measured by increased number of products produced per day).

How might he now summarise the relationship between lunch break duration and staff productivity
A. It has an indirect effect mediated by sugary snack intake
B. It has a direct effect mediated by sugary snack intake
