Final answer:
The correct answer is option c. Van Helsing treats the human Lucy with blood transfusions and garlic, while the vampire Lucy is dispatched by a stake through the heart, according to Bram Stoker's novel 'Dracula'.
Step-by-step explanation:
In the context of Bram Stoker's gothic novel Dracula, the character Van Helsing uses different methods to treat Lucy depending on whether she is human or a vampire. As a human showing signs of vampirism, Van Helsing's treatments for Lucy included blood transfusions to counteract the blood loss she experienced and garlic to ward off further attacks by vampires. This garlic was often placed around her room and neck as a preventative measure.
However, once Lucy becomes a vampire, the treatment shifts drastically. Van Helsing then opts for a more permanent and fatal remedy to end her undead existence, which involves driving a stake through the heart. This act is performed to 'kill' the vampire and release the soul from its cursed existence, allowing it to find peace.
The correct answer to the student's question is thus: C) Blood transfusions and garlic - Human; stake through the heart - Vampire.
