Correct option is C)

C. When vomiting
Solution: Peristaltic movement in the oesophagus helps bolus to move from buccal cavity to stomach. While vomiting, the opposite process happens i.e., foods come to buccal cavity from stomach. So peristaltic movement take place anti clockwise then.
So the correct answer is "When vomiting".
