Option B correctly links stomach receptors to brain signals causing loss of hunger. Other options are incorrect: A incorrectly claims mouth receptors signal stomach to change preference; C incorrectly states mouth receptors stop digestion.

Answer:

B. The sensory receptors in Sam's stomach sent a message to his brain, which made him stop feeling hungry.
