I believe the correct answer here would be B. The values x=2 and y=5 make the equation true. The answer is not A, because the graph could also go through 3 and 6. It is not C because that is not the correct order. The answer is not D because D is absurd and does not make sense.
The anser is 14 I guess because there are 14 marbles in total giving you 14 outcomes
