Answer:
Finally, at the end of Brontë's novel, Jane truly finds herself, thus completing her journey
Step-by-step explanation:
The first option is the exact same as the thesis statement, word for word. Thus, it cannot be used for the conclusion.
The third and fourth options completely deviate from the thesis. The third one brings in characters not relevant to the thesis. The fourth one is about something entirely different.
The second option restates the thesis without copying it. It reiterates the purpose/argument of the essay.
