The correct answer is C) Small intestine. Now, let me explain how we can arrive at this answer.

To understand where absorption begins in the digestive system, we need to have a basic understanding of the digestive process. Digestion is the breakdown of food into smaller molecules, absorption is the process of absorbing these molecules into the bloodstream, and elimination is the removal of waste products from the body.

The digestive system starts the process of digestion in the mouth, where food is mechanically broken down by chewing and mixed with saliva, which contains enzymes that begin the chemical breakdown of carbohydrates. However, absorption does not begin in the mouth.

Next, the food travels down the esophagus into the stomach. In the stomach, food is further broken down by the acidic gastric juices, but absorption does not begin in the stomach either.

After leaving the stomach, the partially digested food enters the small intestine. It is in the small intestine where the majority of absorption takes place. The inner lining of the small intestine consists of specialized structures called villi and microvilli, which increase the surface area for absorption. This lining is also rich in blood vessels, allowing for efficient transfer of absorbed nutrients into the bloodstream. Therefore, the answer is indeed C) Small intestine.

The gallbladder, mentioned in option D, is not involved in absorption. It is an organ that stores and concentrates bile produced by the liver, which is then released into the small intestine to aid in the digestion of fats.

So, to summarize, absorption begins in the small intestine, making option C) the correct answer.
