Explanation:

First Question:

To determine the mineral for red blood cells (RBCs), recall: RBCs need iron for hemoglobin (carries oxygen). Calcium is for bones/muscle, boron for plants, kryptonite is fictional. So iron is correct.

Analyze options: Water is essential. Unsaturated fat (e.g., in oils) is healthy. Vitamins are vital. Saturated fat (in butter, red meat) in excess is unhealthy (raises cholesterol). Thus, saturated fat is not good (in context of excess or comparison).

Answer:

C. Iron
