Final answer:

Step-by-step explanation:
A reasonable possible explanation(s) of the lower profitability for the Mid-Central Region could include: the lower number of stores in the region, which could impact overall sales volume;
less productive sales employees, affecting the ability to generate sales as compared to other regions; and a lower gross margin, meaning the difference between sales and cost of goods sold is smaller, possibly due to higher costs or lower sales prices. Therefore, the correct answer is D. I, II and III.
