Food pipe

Epiglottis
C

None of them
Explanation: 

Detailed explanation-1: -Your esophagus is a hollow, muscular tube that carries food and liquid from your throat to your stomach. Muscles in your esophagus propel food down to your stomach. One of the most common symptoms of esophagus problems is heartburn, a burning sensation in the middle of your chest.

Detailed explanation-2: -Although the small intestine is narrower than the large intestine, it is actually the longest section of your digestive tube, measuring about 22 feet (or seven meters) on average, or three-and-a-half times the length of your body.

Detailed explanation-3: -The esophagus is a muscular tube about ten inches (25 cm.) long, extending from the hypopharynx to the stomach. The esophagus lies posterior to the trachea and the heart and passes through the mediastinum and the hiatus, an opening in the diaphragm, in its descent from the thoracic to the abdominal cavity.

Detailed explanation-4: -the alimentary canal (also called the digestive tract). This long tube of organs makes a pathway for food to travel through the body. It runs from the mouth to the anus (where poop comes out) and includes the esophagus, stomach, and intestines. An adult’s digestive tract is about 30 feet (about 9 meters) long.
