Answer to Question 1

3
Rationale 1: Niacin is vitamin B and therefore water soluble.
Rationale 2: Vitamin C is a water-soluble vitamin and cannot be toxic.
Rationale 3: Vitamin A is lipid-soluble and can be toxic in large amounts.
Rationale 4: Folic acid is a B vitamin and is water soluble.
Global Rationale: Vitamin A is lipid soluble and can be toxic in large amounts. The other vitamins are water soluble and do not pose a risk of toxicity.
