The correct option is B Food particles enter the wind pipe
Hiccups are sudden, involuntary contractions of the diaphragm. It occurs at the time when the voice box (larynx) contracts and the glottis closes. Due to this, the glottis effectively blocks the air intake.
The diaphragm contracts out of rhythm which causes hiccups. There are many causes of hiccups. The major reason for the occurrence of hiccups is food particles entering the windpipe.
