Answer 1

Type C is the most common type of tracheoesophageal fistula (TEF).

Step-by-step explanation:

Type C is the most common type of tracheoesophageal fistula (TEF). Type C TEF occurs when there is a connection between the esophagus and trachea, with a blind upper esophageal segment. This means that the upper part of the esophagus ends in a blind pouch and is not connected to the mouth.
