Enzyme secreted by stomach digests the food but stomach is not digested by this digestive juice because

Wall of stomach is lined with mucus
This is made up of hard cells
It is made up of steel
None of the above

The correct answer is: A. Wall of stomach is lined with mucus.

The stomach is a muscular organ that lies in the upper abdomen. It is responsible for digesting food. The stomach lining is made up of mucus, which protects the stomach from the digestive juices that it produces. The mucus also helps to lubricate the food so that it can be easily digested.

The other options are incorrect because:

  • Option B: The stomach is not made up of hard cells. It is made up of muscle tissue.
  • Option C: The stomach is not made up of steel. It is made up of muscle tissue and connective tissue.
  • Option D: None of the above is the correct answer.

I hope this helps!
