Question

why are fats important for the absorption of certain vitamins? because fats are the only source of vitamins; because all vitamins are water - soluble; because some vitamins are not water - soluble and need fat for absorption; because vitamins are hydrophobic

Explanation:

• Analyze Option 1: Fats are not the only source of vitamins (e.g., fruits/vegetables have vitamins), so this is incorrect.
• Analyze Option 2: Vitamins are either fat - soluble (A, D, E, K) or water - soluble (B, C), so "all vitamins are water - soluble" is wrong.
• Analyze Option 3: Fat - soluble vitamins (A, D, E, K) are not water - soluble. They are absorbed along with dietary fats, so this option correctly explains why fats are important for absorbing certain vitamins.
• Analyze Option 4: Many vitamins (like B, C) are hydrophilic (water - loving), so this is incorrect.

Answer:

C. Because some vitamins are not water - soluble and need fat for absorption
