In the following passage, what best describes the way Ana is characterized?

Ana put her book aside at Nier's request. She knew better than to do otherwise, as Nier was always persistent. He was sure to annoy her into reading the same paragraph half a dozen times if she bothered to ignore his entreaties for attention. He was quite the handful, but for the love of her brother, Ana played along.
"There now, that's a sport," Nier smiled as the book touched the table.
"Ana, I must ask you for one additional favor. Could you pick a card?" He spread a deck of cards before her with a magician's flourish. Her lips tightened, concealing whatever opinion they might have pronounced had there been any point in pronouncing it. She chose a card from the middle of the deck.

A. Direct characterization tells readers Ana is an irritable person who always upsets Nier.

B. Indirect characterization shows readers Ana is a fan of magic and is happy to play along with her brother.

C. Indirect characterization shows that Ana is being patient out of love for her brother.
