Answer:
Mrs. Mallard bursts out weeping when she hears the news of her husband’s death.
Step-by-step explanation:
The correct answer is that Mrs. Mallard bursts out weeping when she hears the news of her husband's death.
The other options are all part of the irony in the story in that they all suggest the opposite of what was really said.
In the midst of Mrs. Mallard’s grief, she sees and hears the signs of spring. This sentence have the word grief but then she sees and hears the signs of spring, which is quite ironic as they she is supposed to be thinking of sad and gloomy things. The other sentences are also ironic as they aren't really what they mean.
When she sees her husband, Mrs. Mallard dies of heart failure.
The doctors diagnose the death of Mrs. Mallard as “joy that kills.”
Mrs. Mallard did die and at the exact time she sees her husband is alive, but not because of the relief of his safety but rather in the joy of knowing that she is finally free from him.
