Answer:
The correct answer is A: All of the answer are correct
Step-by-step explanation:
ABC defines production as consisting of a variety of activities, and it assigns costs to those activities. An activity cost pool is an aggregate of all the costs associated with performing a particular business task, such as making a particular product. By pooling all costs incurred in a particular task, it is simpler to get an accurate estimate of the cost of that task.
Cost pool is created for those costs more closely aligned with the production of goods or services. It is very common to have separate cost pools for each product line. If production batches are of greatly varying lengths, then it has to consider creating cost pools at the batch level, so that it can adequately assign costs based on batch size.
To conclude, the creation of a cost pool and the subsequent assignment of costs will vary according to the length of production and the possibility to discriminate and assign costs.
