c. Cost drivers are activities or decisions that create costs.
d. Quality is an overarching cost driver.
Step-by-step explanation:
Cost driver is defined as a factor that causes change in the cost of an activity. It is unit change of an activity that causes change in the cost of that activity.

Quality is considered an overarching cost driver because the higher the quality of a product the greater cost incurred to produce it.
