The correct answer is D. They can use the paw to wish Herbert alive again.
Step-by-step explanation:
"The Monkey's Paw" is a fictional story, in which a couple (Mrs. White and Mr. White) used a monkey's paw to make three wishes; however, using the paw has terrible consequences they did not imagine. In the case of the first wish, the couple wishes money to pay the mortgage and this causes the death of their son Herbert.
Later, Mrs. White has an epiphany or strong revelation as she realizes she can use another wish to reverse the death of her son. This epiphany is described in the excerpt "The monkey’s paw!"...The other two wishes," she replied rapidly. "We've only had one." According to this, the epiphany or revelation that motivates Mrs. White to use the paw again despite the negative consequences is that she realized "They can use the paw to wish Herbert alive again".
