• C.
• D.

Answer: (D)

Verified step by step guidance

1. Step 1: Understand that fatty acid absorption is influenced by chain length and degree of saturation. Short-chain fatty acids are absorbed more quickly than long-chain fatty acids because they are more water-soluble and do not require micelle formation for absorption.
2. Step 2: Analyze the chemical structures provided in the images. Each structure represents a fatty acid with varying chain lengths. Count the number of carbon atoms in each fatty acid chain to determine the chain length.
3. Step 3: Identify the fatty acid with the shortest chain length. For example, the fatty acid with the fewest carbon atoms will likely be absorbed the fastest.
4. Step 4: Consider the role of micelle formation in absorption. Longer-chain fatty acids require micelles for transport across the intestinal lining, which slows down their absorption compared to short-chain fatty acids.
5. Step 5: Based on the analysis, select the fatty acid with the shortest chain length as the one most likely to be absorbed quickly by the body.
