A successful coffee stand that serves the workers in a large office building plans to increase its profits by adding oatmeal-a hot cereal popular among the workers-to its menu. The manager says that oatmeal is "the ultimate convenience food" because it can be served by the cup, as coffee is; further, offering oatmeal will enable the stand to get into the breakfast business without making a large investment, because it does not require elaborate cooking equipment.

Which of the following would, if true, most strengthen the likelihood that the manager's plan will achieve its goal?

A:Some of the office building's businesses have recently begun providing free coffee to their employees.

B:The ingredients needed to make oatmeal are inexpensive and do not spoil easily the way many fresh breakfast foods typically sold at coffee stands do.

C:In order to offer more flexible schedules to their workers, several businesses in the office building will soon be expanding their hours.

D:Supermarket sales of oatmeal and other cereals slowed this year following large gains last year.

E:Oatmeal manufacturers have recently reduced their oatmeal offerings, which had included oatmeal in microwaveable cups and convenient cereal bars made with rolled oats.
