Answer:
All of the above would use process costing.
Explanation:
Process costing can be defined as a method of assigning manufacturing costs whereby the cost of each unit produced is assumed to be the same cost for every unit.
Process costing is most commonly applied when goods are produced in large numbers and when the costs linked to individual units cannot be easily differentiated from each other.
Under process costing, costs rise over a fixed period of time, and are then assigned to all the units produced throughout that period.
