A : Liver assist in digestion of fat.
R : Hepatic secretion contains bile salts which emulsify fat

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 Solution:**

1. **Understanding the Assertion (A):**
- The assertion states that "The liver assists in the digestion of fat."
- This statement is true because the liver plays a crucial role in the digestion process, particularly in the emulsification of fats.

2. **Understanding the Reason (R):**
- The reason states that "Hepatic secretion contains bile salts which emulsify fat."
- This statement is also true. Bile salts, which are secreted by the liver, help in breaking down fats into smaller droplets, a process known as emulsification.

3. **Connecting Assertion and Reason:**
- The reason provided explains how the liver assists in fat digestion. The bile salts produced by the liver are responsible for emulsifying fats, making it easier for digestive enzymes to act on them.

4. **Conclusion:**
- Since both the assertion and the reason are true, and the reason provides a correct explanation for the assertion, we can conclude that both statements are correct and related.

5. **Final Answer:**
- The correct answer is that both the assertion and reason are true, and the reason is the correct explanation of the assertion.
