A : Trypsin is secreted in pancreatic juice as trypsinogen.
R : Zymogenic forms protect pancreas from autodigestion.

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 is 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 statements, then mark (4).

Answer

### Step-by-Step Text Solution

1. **Understanding the Assertion**: The assertion states that "trypsin is secreted in pancreatic juice as trypsinogen." This is true because trypsin is indeed secreted by the pancreas in an inactive form known as trypsinogen.

2. **Understanding the Reason**: The reason states that "zymogenic forms protect the pancreas from autodigestion." This is also true. The pancreas produces digestive enzymes, and if these enzymes were active while still in the pancreas, they would begin to digest the pancreatic tissue itself, leading to autodigestion.

3. **Linking Assertion and Reason**: The reason provided explains why the assertion is true. Trypsinogen (the zymogen form of trypsin) is secreted to prevent the active enzyme from digesting the pancreas. Hence, the reason is a correct explanation of the assertion.

4. **Conclusion**: Both the assertion and the reason are true, and the reason correctly explains the assertion. Therefore, the correct answer is that both the assertion and reason are true, and the reason is the correct explanation for the assertion.

### Final Answer
Both Assertion and Reason are true, and the Reason is the correct explanation for the Assertion.
