Final answer:
Mme. Defarge visits Lucie's house in 'A Tale of Two Cities' to collect information about Darnay's activities. Her motives are tied to the revolution and espionage. The correct option is D.
Step-by-step explanation:
In the novel A Tale of Two Cities by Charles Dickens, Mme. Defarge came to Lucie's house primarily to gather information about Darnay's activities.
She was a key revolutionary figure, and her visit was marked with covert hostility and was meant for espionage rather than for altruistic reasons.
Mme. Defarge's visit is part of the ironic juxtapositions that Dickens uses to portray the tumultuous times of the French Revolution, showing that not even the innocent can avoid being touched by the pervasive atmosphere of suspicion and betrayal.
