Answer:
C. b, c, a, d
Explanation:
The Costing System includes various stages.
The first stage we need to identify number of activities performed and then find the estimates of the total cost.
In the next stage we need to find the cost driver for each activity and then estimate the quantity of each driver's allocation base.
Then in Next stage we need to solve and compute the allocation rate for each activity.
And Then finally we need to find any Indirect cost applied to cost of the object.
Hence The Sequence would be b, c, a, d.
