Answer:
The correct answer is option B) Mr. White uses his third and final wish.
Step-by-step explanation:
The climax is the moment when the maximum peak in a story develops.
The moment of greatest tension will reach its peak in the climax, and that just happens when Mr White uses his third wish to make the monster that was supposed to be his son disappear.
If we think about that situation, the plot becomes very tense, with knocks on the door getting louder, and Mrs. White desperately going to see her son while Mr. White knew that if he opened that door they would die.
That's when he asks that monster disappear and the climax reaches its maximum point.
Given this information we can say that the correct answer is option B.
