Answer:
c. The cost of goods sold to be overstated and
d. Net operating income to be understated
Explanation:
Overheads are applied based on indirect costs estimated, and that the cost do not include any direct cost.
If direct cost is also added then it will be twice applying such cost, this will clearly reflect that the overhead rate is over applied, and thus this will result in cost of goods sold overstated.
This is due to high rate charged, accordingly as cost will be more than the actual cost, net operating income will also be understated as cost is more and revenue is less.
Thus, statement C and statement D is correct.
