AI Generated Solution

The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Assertion**: The assertion states that "Bile helps in emulsification of fat." This is true because bile, which is produced by the liver and stored in the gallbladder, contains bile salts that play a crucial role in breaking down large fat globules into smaller droplets. This process increases the surface area for enzymes to act upon, facilitating fat digestion. 2. **Understanding the Reason**: The reason provided states that "Bile salts help in incorporating fatty acids and glycerol into water-soluble droplets called chylomicrons." This is also true. After fats are emulsified by bile salts, they are further broken down into fatty acids and glycerol. These components are then packaged into chylomicrons, which are lipoprotein particles that transport lipids through the lymphatic system and into the bloodstream. 3. **Analyzing the Relationship**: Both the assertion and the reason are true. Furthermore, the reason explains the assertion well. The emulsification of fats by bile allows for the subsequent absorption of fatty acids and glycerol, which are then incorporated into chylomicrons. 4. **Conclusion**: Since both the assertion and reason are true, and the reason provides a correct explanation for the assertion, the correct answer is: "If both assertion and reason are true, the reason is the correct explanation of the assertion." **Final Answer**: Both assertion and reason are true, and the reason is the correct explanation of the assertion. ---
