Yes, the correct answer is B. The mouth, small intestine, and kidneys have functions related to the intake, digestion, absorption, and elimination of food and its wastes.

To find the answer, we can look at the functions of each organ individually.

1. The mouth: The mouth plays a role in the intake of food. It helps in chewing and breaking down food into smaller particles, making it easier to swallow and digest.

2. The small intestine: The small intestine is the primary site for digestion and absorption of nutrients from the food we eat. It releases enzymes that break down complex molecules into simpler forms that can be absorbed by the body.

3. The kidneys: The kidneys function in filtering the blood and removing waste products, excess water, and electrolytes from the body. They also play a crucial role in maintaining the body's fluid balance and regulating blood pressure.

Considering these functions, option B correctly summarizes the functions of the mouth, small intestine, and kidneys. They are involved in the entire process of digestion, absorption, and elimination of food and its wastes.
