Many traditional costing systems:

a. produce results far superior to those achieved with activity-based costing. write off manufacturing overhead as an expense of the current period.

b. use a host of different cost drivers (e. g., number of production setups, inspection hours, orders processed) to improve the accuracy of product

c. costingbine widely varying elements of overhead into a single cost pool.

d. trace manufacturing overhead to individual activities and require the development of numerous activity-costing rates.

The correct answer is letter "D": combine widely varying elements of overhead into a single cost pool.
