Answer :
The correct answer is B) weighted-average.
The pricing of issues from inventory must be deferred until the end of the accounting period under the following method of inventory valuation: "weighted-average."
The method of inventory "weighted-average" is used by the accountants when they want to select the average cost of production to a good. This method of inventory is better used if the inventory items are blended, making it difficult to determine a specific cost to each unit of the product. Or when the goods are identical or so similar that it is not possible or easy to determine a coast to each unit.
