Answer:
b.purchases are larger than the cost of goods sold by the amount that inventories increased
Explanation:
As we know that operating cash flow refers to the cash amount i.e to be generated through day to day activities
So if there is an increase in inventories and the same is to be deducted from the net income because as the cost of goods sold is reported on the debit side of the income statement but if the purchase amount is more than the cost of goods sold so to maintain the accrual basis we need to do the adjustments.
