Answer : Option A
Explanation :
The stomach does not digest itself because it is lined with epithial cells, which produce mucus. This forms a barrier between the lining of the stomach and the contents. Enzymes, which make up part of the digestive juices are also secreted by the stomach wall, from glands with no mucus barrier.
