D. A profit margin of 15-20 percent.

Explanation:

Ben and Alison have determined to run a business that would require efforts to set it up productively, so they cannot have relaxing days at home. After that in order to establish their business efficiently,  they would have to toil endlessly and thus, they can not restrict their jobs to days only. Then, the high ratings by national organizations can never be assured even after years, for them, it's just the beginning. Thus, the only one left is the profit margins(D) as if one starts a business, its sole aim is to earn profit at first, other purposes come later.
