To maximize the number of ribbons won by the top two students, we need to minimize the number of ribbons won by the remaining three students. Since each student won at least one ribbon and since no two students won the same number of ribbons, the minimum number of ribbons won by the lowest scoring three students is 1, 2 and 3.
Since the three lowest number of ribbons won was 1, 2, and 3 ribbons, there are a total of 14 ribbons left to be shared between the 2 people winning the two highest ribbon counts.
Note that no two students won the same number of ribbons; therefore, it is not possible that the top two students each won 7 ribbons. In order to make the second greatest number of ribbons won the largest, we need the greatest number of ribbons won to be equal 8, and thus the second greatest number is 6. Alternatively, it is also possible that the lowest number of ribbons won was 1,2 and 4 and the remaining two students won 6 and 7 ribbons, respectively.
Answer: B
