Answer:
The correct answer is letter "B": inventory must be counted at the end of each accounting period.
Explanation:
The Periodic Inventory System is an approach of keeping track of the inflows and outflows of the inventory of a company after determined periods. Starting the year, companies using this inventory method count the number of items in their inventory which will vary during the course of a period and by the end of it another count is made to find out the difference between the starting and ending inventory. The calculation helps to find out the Cost of Goods Sold by the firm (COGS).
