The correct answer is: A. materials are subject to natural wastage.
The inflated price method of valuing material issues is a method of accounting for materials that are subject to natural wastage. This method assumes that a certain amount of material will be wasted during the production process, and it values the materials at a higher price to account for this waste. This method is most commonly used in industries where there is a high level of natural wastage, such as the mining and manufacturing industries.
The inflated price method is not suitable when prices are rising or falling. When prices are rising, the inflated price method will result in an overstated cost of goods sold. When prices are falling, the inflated price method will result in an understated cost of goods sold.
