Answer:
B. diseconomies of scale
Explanation:
Diseconomies of scale occurr when a business experiences rising costs when it expands, either in output capacity, number of plant locations, or both.
In this case, Temper Company would experience diseconomies of scale because if it expanded its output capacity to China, it would incurr increasing transportation costs to the point of offsetting any gains made because of outsourcing. In other words, diversifying plant locations is negative for Temper Company, and as a result, this firm is suffering from diseconomies of scale.
