In the story: MacBeth- Why do the noblemen think Malcolm and Donnalbain fled? A. To find the King's killer
B. Because they were guilty
C. They had royal duties to perform

I would contend that the right answer is actually the B) Contains a detail that appeals to the sense of taste.

Explanation: Just to elaborate a little on the answer, it can be added that in this line the author is using imagery, with the goal of appealing to the reader's physical senses and creating a specific image in his or her mind. This is a very graphic description of food. It is almost impossible not to picture the fleshy and salty prawns with their black, slippery, and annoying thin veins being removed by Tan's mother. Tan was somehow embarrased of the food that her Chinese family was preparing for the minister's family, and by being so descriptive she gets the reader to better understand her point.
