________ aid (s) in the emulsification of fat.

Correct option is B

The correct answer is (B) Bile salts.

·         Bile salts, secreted by the liver and stored in the gallbladder, play a crucial role in the emulsification of fats during digestion.

·         Emulsification is the process of breaking down large fat globules into smaller droplets, increasing the surface area for enzymes to act upon.

Explanation of Other Options:

• Vit–K Trypsin:
• Vitamin K is involved in blood clotting, not fat digestion.
• Trypsin is a protease enzyme that breaks down proteins, not fats.
• HCl:
• Hydrochloric acid is secreted in the stomach and helps in protein digestion, not fat emulsification.
• Pepsin:
• An enzyme in the stomach that digests proteins, not fats.
