Final answer:
In this scenario, the dependent variable is the number of times the stapler jams, while the independent variable is the number of papers being stapled.
Step-by-step explanation:
The dependent variable is the variable that is affected by the change, while the independent variable is the variable that is manipulated. In this scenario, the correct option is d) Independent: Number of times it jams, Dependent: Number of papers.
