The correct option is C. Identifying specific cost drivers is not a task usually associated with activity-based costing (ABC). Since heterogeneous products are distinct from other products, process costing does not apply to them.
Tracing direct labor expenses back to product and customer contracts and allocating manufacturing overheads based on current direct labor hours to contracts were the two key responsibilities of the ABC system.
The advantage of the activity-based costing approach is not the reduction of prime cost. Reason: In an activity-based cost system, the products and manufacturing inputs are given a special cost measure. The ABC system employs a system that more precisely allocates expenses to items.
