Expression of Ideas practice question

While researching a topic, a student has taken the following notes: - A hospital can buy one scanner of type A or two of type B for the same money. - Type A produces clearer images. - Type B scanners are quicker, so two of them can scan three times as many patients a day as one type A. - The hospital's waiting list for scans is eleven months long. The student wants to justify choosing two type B scanners.

Which choice most effectively uses relevant information from the notes to accomplish this goal?
