To find the wrong statement from the given options, we will analyze each statement one by one. ### Step-by-Step Solution: 1. **Analyze Option 1**: "Amnion is the outer layer containing amniotic fluid that acts as a shock absorbent to the soft embryo." - The amnion is actually an inner layer, not the outer layer. It does contain amniotic fluid, which acts as a shock absorber for the developing embryo. Thus, this statement is incorrect. 2. **Analyze Option 2**: "Yolk sac is a fetal membrane that helps in the nourishment of the embryo in general." - The yolk sac does play a role in the nourishment of the embryo, especially in the early stages of development. This statement is correct. 3. **Analyze Option 3**: "In mammals, allantois is not excretory in function." - In mammals, the allantois does not serve an excretory function; instead, it contributes to the formation of the umbilical cord and the placenta. This statement is correct. 4. **Analyze Option 4**: "Cori allantoic membrane develops and contributes much to the development of the placenta." - The chorion and allantois do contribute to the formation of the placenta in mammals. This statement is also correct. ### Conclusion: After analyzing all the options, we can conclude that the wrong statement is **Option 1**. ### Final Answer: The wrong statement is **Option 1**: "Amnion is the outer layer containing amniotic fluid that acts as a shock absorbent to the soft embryo." ---
