Membrane that gives protection to embryo from external shocks is

Options

A. Amnion
B. Alantois
C. Chorion
D. Placenta.

Answer

To solve the question "Membrane that gives protection to embryo from external shocks is," we can follow these steps:

### Step 1: Understand the Question
The question is asking for the specific membrane that protects the embryo from external shocks. This indicates that we need to identify the correct extra embryonic membrane involved in this protective function.

### Step 2: Review the Options
The options provided are:
- A. Amnion
- B. Allantois
- C. Chorion
- D. Placenta

### Step 3: Analyze Each Option
- **A. Amnion**: This is a membrane that surrounds the embryo and contains amniotic fluid, which cushions the embryo and protects it from external shocks.
- **B. Allantois**: This membrane is primarily involved in waste storage and gas exchange, not directly in protection from shocks.
- **C. Chorion**: This membrane is involved in nutrient transfer and gas exchange but does not provide cushioning.
- **D. Placenta**: This is an organ that connects the developing fetus to the uterine wall but is not a membrane that directly protects the embryo from shocks.

### Step 4: Identify the Correct Answer
From the analysis, it is clear that the **Amnion** is the membrane that provides protection to the embryo from external shocks due to the cushioning effect of the amniotic fluid it contains.

### Conclusion
The correct answer to the question is **A. Amnion**.
