A : Fertilin protein is present in the egg membrane
R : it helps in agglutination reaction .

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion then mark (1)
B. If both Assertion & Reason are true but the reason is not the correct explanation of the assertion then mark (2)
C. If Assertion is true statement but Reason is false then mark (3)
D. If both Assertion and Reason are false statement then Mark (4)

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion (A)**: The assertion states that "Fertilin protein is present in the egg membrane."
- To evaluate this, we need to know the location of the fertilin protein. Fertilin is a surface protein associated with sperm, not the egg membrane.

2. **Understanding the Reason (R)**: The reason states that "it helps in agglutination reaction."
- Agglutination refers to the clumping of cells, which is not the primary function of fertilin. Instead, fertilin plays a crucial role in the fertilization process, specifically in the interaction between sperm and the egg.

3. **Evaluating the Truth of Assertion and Reason**:
- Since fertilin is not present in the egg membrane, the assertion (A) is **false**.
- Since fertilin does not assist in agglutination but rather in fertilization, the reason (R) is also **false**.

4. **Conclusion**: Both the assertion and the reason are false. Therefore, the correct answer to the question is that both A and R are false.

5. **Selecting the Correct Option**: Based on the evaluation, the correct option is option 4, which states that both the assertion and the reason are false.
