The correct option is D A - Oesophagus ; B - Stomach ; C - Intestine
The oesophagus or food pipe takes the food from the mouth to the stomach.
The stomach contains acids that help in the process of digestion.
The liver, gallbladder and pancreas secrete digestive juice which helps in breaking down the food even further.
From the stomach, food goes into the intestines which help in the absorption of nutrients.
