The correct Answer is:
### Step-by-Step Solution: 1. **Definition of Allantois**: The allantois is a membranous sac that is part of the developing embryo in mammals. It plays a crucial role in various physiological processes. 2. **Functions of Allantois**: - **Nutrition**: The allantois serves as a site for nutrient exchange. It helps in the transport of nutrients from the mother to the developing embryo. - **Respiration**: The allantois is involved in gas exchange. It facilitates the transfer of oxygen to the embryo and the removal of carbon dioxide. - **Excretion**: The allantois collects waste products produced by the embryo. It helps in the excretion of these waste materials, preventing toxicity within the developing embryo. 3. **Conclusion**: Therefore, the allantois in mammals is primarily responsible for three key functions: nutrition, respiration, and excretion. 4. **Correct Option**: Based on the functions discussed, the correct answer to the question is Option C: Nutrition, excretion, and respiration.
