Solution
The correct option is B 5
From the graph,
Number of students who like blue = 6
Number of students who like green = 1
Difference in number of students who like blue more than green can be calculated by subtracting the two numbers.
That is,
(6 - 1) = 5
Thus, 5 more students like blue more than green.
