Answer:
She feels partially responsible for John's affair because she feels she wasn't worthy of his love.
Explanation:
The given question refers to <em>The Crucible</em>, a play written by Arthur Miller. In this play, Miller dramatized and fictionalized the story of the Salem witch trials that took place in the Massachusetts Bay Colony during 1692 and 1693.
The given quote is from the fourth act of the play. John Proctor stands accused of practicing witchcraft, compromised by his relationship with Abigail, with whom he had an affair. His wife, Elizabeth, is sharing her true feelings with him about the affair. Because of it, their relationship grew cold, but here, she confesses that she feels partially responsible for it. Their relationship wasn't filled with any passion, and she realizes why he sought passion outside of it. She feels unworthy of his love, describing her detachment from her husband as <em>keeping a cold house</em>.
This is why the last option is the correct one.
