I believe that It is C, because although the passage does focus on Mathilde's love for expensive things, broadly the subject is how Mathilde is discontent with the lifestyle she is now living, and D is too broad, and B is also too broad.
Well, since we know an antonym is the opposite, and patronize means to treat someone kindly, we can choose C. scornful. :)
<span>These lines mean that A. the sun is coming up and the fairies should leave. This person says that "he hears the morning lark," which means that the night is ending and the sun is going to come up very soon. This means that the faries should leave as they shouldn't be seen during the day, as night is their realm. These lines do not provide enough information for these other options to be the correct ones. </span>
