The only possible incorrect answer is (A), and I'll explain why the other three are correct.
(B): The y-axis represents the number of tokens won, while the x-axis represents the time played in minutes. By looking at the graph at y = 3, we have an open circle at x = 4. This means that the player earned 3 tokens in the span of 4 minutes, and thus, (B) is correct.
(C) and (D) are correlative. By winning the game, it took the player 10 minutes to do so. This means that the player took 10 minutes to play the game, and because they won all six tokens, they won the game.
(A) is incorrect, because the interval between the third and fourth token isn't the longest, which indicates that the fourth token didn't take the longest to win. Thus, we can conclude that (A) is false.
