a. the bar-sound association disappears.
b. the extinction burst disappears.
c. the sound-food association remains intact.
d. Extinction occurs more rapidly than when the sound is also absent.
b. the extinction burst disappears.

The sound-food association disappears because the sound now occurs without being followed by food. With the sound still produced by bar presses, it takes longer to reach the extinction criterion.
