When you are swallowing, sometimes food or liquid can "go down the wrong pipe." This means that the material has entered the respiratory tract instead of the digestive tract. The correct answer to the question is:
C) Some material went into the trachea
Let's break it down further:
What Happens When You Swallow:
Normally, when you swallow, the food or liquid is directed down the esophagus (the tube that leads to the stomach).
At the same time, a small flap called the epiglottis closes over the trachea (the windpipe) to prevent anything from going into your lungs.
Down the Wrong Pipe:
If some material accidentally enters the trachea, it goes "down the wrong pipe."
This can happen if the epiglottis doesn't close quickly enough.
Resulting Reaction:
This can cause coughing or choking as your body attempts to expel the material from the airway to protect your lungs.
Understanding this can help prevent it from happening by chewing food well and swallowing carefully.
