Final answer:
The correct answer is B. The Inventory account is adjusted at the end of the accounting period in the periodic inventory method. This contrast with the perpetual inventory method, where inventory and cost of goods sold accounts are updated continuously.
Step-by-step explanation:
The true statement about the periodic inventory method that is not true for the perpetual inventory method is B. The Inventory account is adjusted at the end of the accounting period. In the periodic system, the cost of goods sold is calculated at the end of the period by taking a physical inventory count to determine the ending inventory and thus the cost of goods sold for the period. The inventory account does not change with each sale or purchase during the period. In contrast, under the perpetual inventory system, the inventory account is updated continuously with each transaction affecting inventory, and the cost of goods sold is recorded at the point of each sale.
