Option 4 states that the liver and pancreas contribute to mechanical and chemical digestion, respectively. This means that the liver primarily aids in mechanical digestion, which involves the physical breakdown of food into smaller pieces. The liver does not directly participate in chemical digestion, which involves the breakdown of food molecules through the action of enzymes. On the other hand, the pancreas plays a crucial role in chemical digestion by secreting digestive enzymes into the small intestine. These enzymes help break down carbohydrates, proteins, and fats into smaller molecules that can be absorbed by the body. Therefore, option 4 is the correct answer.
