In The Glass Menagerie, even though the Wingfields live in a run-down apartment in the city, Amanda is concerned about being proper and keeping up appearances. Which detail from the play best supports this inference?

A. AMANDA: "I took that horrible novel back to the library-yes! That hideous book by that insane Mr. Lawrence. [Tom laughs wildly.] I cannot control the output of diseased minds or people who cater to them -[Tom laughs still more wildly.] BUT I WON'T ALLOW SUCH FILTH BROUGHT INTO MY HOUSE! NO, no, no, no, no!"
B. LAURA [shakily]: "How was the DAR. meeting? [AMANDA slowly opens her purse and removes a dainty white handkerchief which she shakes out delicately and delicately touches to her lips and nostrils.] Didn't you go to the DAR. meeting, Mother?"
C. AMANDA: "We can't have a gentleman caller in a pigsty! All my wedding silver has to be polished, the monogrammed table linen ought to be laundered!"
D. AMANDA: "Do you realize he's the first young man we've introduced to your sister? It's terrible, dreadful, disgraceful that poor little sister has never received a single gentleman caller."
