Answer:D.None of the option is correct, the correct answer is Buy; savings=$203,000
Step-by-step explanation:
The firm will Incurred the total fixed overhead it decides to make.
The total cost of making 6000 units is $163*6000=$978,000
The total cost of buying is $144*6000= $864,000 and when we deduct $89,000 to be saved from fixed overhead by buying we have a total cost of( $864,000-$89,00) =775,000.
This invariably means the company will save ($978,000-$775,000) which is equal to= $203,000 by buying.
