Answer:
(B) Cost of goods purchased
Explanation:
While a merchandising company buys goods from its suppliers (goods purchased) and adds this to its opening inventory to determined the quantity of goods it has available for sale (goods available for sale), a manufacturing firm makes the goods to be sold (goods manufactured) and add to its opening inventory of finished goods to determine the same metric (quantity of goods available for sale).
This relationship can be seen when the trading account of both firms are compared.
